Jessica Simpson has reached her target weight.
The reality star and mother to daughter Maxwell, 21 months, and son Ace, eight months, has shed 50lbs of her baby weight and celebrated by posting shots of herself in a white dress on Instagram.
Under one picture she wrote: "First time rocking a white dress this year ...but not the last!! Thanks @weightwatchers! (sic)"
Alongside another picture of her wearing a T-shirt, she added: "...AND a white T-shirt!!#goalreached thx (sic)"
Jessica - who is engaged to be married to Eric Johnson - also posted a picture of Maxwell, showing how she has inherited her famous blonde hair colour.
She captioned it: "The most beautiful girl in the world."
She also posted a picture of her holding Ace, saying he was the "most handsome boy in the world".
Jessica - who is a spokesperson for Weight Watchers - has previously said she has set a date for her wedding to former NFL star Eric, 34, and is planning to stay in shape for her big day.
She said: "I think it's about time! Knowing that I have the wedding coming up is an incentive to stay on Weight Watchers, count my points and stay in the gym. I mean, when you see my dress, you'll know."

Angelina Jolie finds it funny how people think she makes a great villain.
The 38-year-old actress appears as the titular wicked witch in 'Maleficent' and admits she was always drawn to the character when she was younger.
She told Entertainment Weekly magazine: "It is really funny when people say you'd be obvious for a great villain. She was just my favourite as a little girl. I was terrified of her, but I was really drawn to her. I loved her.
"There were some discussions about it before I got the part, and I got a phonecall from my brother, who said, 'You've got to get your name on the list for this!"
The star raises six children with her fiance Brad Pitt - Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Vivienne and Knox, five - and secretly told them the film's plot to gauge their reaction.
She added: "I told my kids I was playing Maleficent and they said, 'She's so scary!' and I said, 'Let me tell you the real story, but you can't tell anybody.'
"And I put them in the room and I told them the [film's] story. So this was my test too, like any parent. And the next day I heard Shiloh getting into a fight with another kid, defending Maleficent, saying, 'You don't understand her!' They got into a bit of an argument and I thought, 'That's the reason to do the film.' "

Scarlett Johansson's pregnancy was a "welcome surprise".
The 'Avengers Assemble' star announced she is having with her first child with fiancè Romain Dauriac earlier this week but a friend says they have known about it for some time.
The source told UsMagazine.com: "She's about four months along. The baby was a welcome surprise."
The insider says Scarlett has been looking forward to telling people of her happiness, adding: "She's just excited to share the news."
The actress had previously talked about her desire to start a family at the end of last year, saying in December: "I would like to have my own family, that would be nice.
"They say it's never the right time and I am sure that's true, but I think you have to plan it like anything else.
"At some point it is something I look forward to."
Scarlett, 29, and Romaine, 31, got engaged in August last year after he proposed with a vintage Art Deco ring.
The 'Captain America: The Winter Soldier' star has previously said she and Romain don't want to "rush through" tying the knot, as "being engaged is an exciting time to enjoy and to really savour."
The marriage will be Scarlett's second after she was previously wed to actor Ryan Reynolds between 2008 and 2011.

Kim Kardashian will get $1 million for every year she stays married to Kanye West.
The couple have signed a prenuptial agreement ahead of their forthcoming wedding this spring, in which Kanye has been very generous toward his future spouse.
A source told RadarOnline.com: "The entire process for the prenup for Kim and Kanye has been extremely easy, and relatively drama free.
"Kanye didn't even think the couple needed a prenup, and was ready to give Kim carte blanche to all of his financial assets. Yes, he loves Kim that much."
The source adds drawing up the document was much easier than the last time Kim, 33, married, to basketball player Kris Humphries, in 2011, a union which lasted just 72 days.
The source added: "There is a huge difference from Kim's prenup with Kris Humphries ... the preparation of their agreement went on for several months. It was long and tedious."
The agreement states Kim will get $1 million a year for as long as she stays married, with a cap at ten years. Should they divorce she would keep all gifts given to her by 'New Slaves' rapper Kanye. The couple's still incomplete Bel Air mansion will also be in Kim's name, even though Kanye has paid for the majority of it, and she will also benefit from one of Kanye's life insurance policies, valued at $20 million, even in the event of a divorce.
According to estimates Kanye is worth $100 million, while Kim - who was also married to Damon Thomas from 2000 to 2004 - has a personal fortune of around $40 million from her clothing line and promotional appearances.
No custody arrangements for their eight-month-old daughter, North, are included in the prenuptial document.
The insider added: "The couple are focused on the wedding and looking forward to spending the rest of their lives together. Kim is head over heels in love with Kanye, and knows this is forever. Despite having been married twice before, Kim is treating this wedding as her one and only."
Kim and Kanye are said to be marrying in Paris, France on May 24.

Angelina Jolie and Brad Pitt don't want their children to be actors.
The couple raise six kids together - Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Vivienne and Knox, five - and despite letting Vivienne have a cameo in her new film 'Maleficent', Angelina is not encouraging them to become screen stars.
She told Entertainment Weekly magazine: "We think it's fun for our kids to have cameos and join us on set, but not to be actors. That's not the goal for Brad and me at all. I think we would both prefer that they didn't become actors. "But she was four at the time and other three and four year old [actors] really wouldn't come near me. Big kids thought I was cool - but little kids didn't really like me. So, in order to have a child that wants to play with [Maleficent]... it had to be a child that really liked me and wasn't afraid of my horns and my eyes and claws, so it had to be Viv."
Angelina added Pax was incredibly scared when he first saw her in full make-up as the titular wicked witch, he ran away.
She added: "When Pax saw me for the first time he ran away and got upset. I thought he was kidding, so I was pretending to chase him until I actually found him crying. I had to take off pieces [of the make-up] in front of him to show him it was all fake and not freak him out so much."

Justin Bieber has reunited with Selena Gomez.
The 'Never Say Never' singer has been spotted looking close with his ex in the city of McAllen in Texas this morning (07.03.14), a day after he stormed out of a legal deposition when he was quizzed about her.
The pair - who were first linked in 2010 but split in January 2013, only to get back together again briefly at the beginning of this year - were seen having breakfast at local restaurant Don Pepe's but refused to take photos during their meal.
Selena had pork chops with salsa, while the Justin opted for traditional Mexican dish Huevos Rancheros, according to E! news.
The pair then headed to flower shop LA Imports, where spies say they were hugging and talking about flowers. They then made their way to Perfumeria La Versailles to look around.
Selena is in her home state ahead of a show at Hidalgo State Farm tomorrow (08.03.14), which will be her first since she completed a stint in rehab in January.
Earlier this week Justin raised eyebrows when he posted a picture of his former love in an elegant Emilio Pucci dress for the Vanity Fair party after The Oscars with the caption: "The most elegant princess in the world."
Justin, 20, has recently found himself in a number of legal troubles due to his behaviour in the US and his native Canada, and his uncle, Brad Bieber, thinks his actions were down to him missing Selena.
He said: "How would you feel if your first love didn't work out? How would you feel if that relationship went sour and then it became public and you had no chance to heal or sort out your own emotions and feelings? He is just a brokenhearted, lost little boy."

Lindsay Lohan has Oprah Winfrey on speed dial.
The recovering actress has been mentored by the talk show star since she completed a 90-day court ordered stint in rehab last year, and says she feels blessed to have such a strong bond with her.
She told Extra TV: "I love that I can call Oprah on the phone, and be like, 'Oprah, can we talk right now?' and she calls me within two minutes. I have to trick her into leaving voicemails, so I can just have Oprah's voicemails ... she's the coolest person ever."
Lindsay, 27, has also filmed a docu-series for Oprah's OWN network which she is keen to stress isn't a reality show, and she says she had no control over what made the final cut.
She added: "I did it because it's not a reality show, it's pretty raw. Obviously it's TV, so things will be edited in certain ways to get ratings, which I can't control, but I do know that my intentions going into it were really pure and really honest. I appreciate all that's happened and all that [Oprah has] done for me."

Nicholas Hoult says fame hasn't changed Jennifer Lawrence.
The British star first started dating the 'American Hustle' actress in 2011 and has known her through her Oscar win for Best actress last year and a further nomination this year, and says despite all the accolades, she's still the same person.
He told VMan magazine: "The privacy thing obviously changes but the rest pretty much stays the same.
"It's like that thing whereby you don't believe your own hype. Enjoy the good times, but don't get swept away with it. And I think that's something she's capable of doing and that's what makes her special, but yeah, it is very odd, and I am just kind of a bystander in many ways.
"It is well-deserved for her. I haven't really seen any change in her."
Nicholas, 24, first met Jennifer on the set of 'X-Men: First Class' in 2011 and after a break in early 2013 they got back together when they were filming forthcoming sequel 'X-Men: Days of Future Past', which he says was a great experience because it meant they were able to spend plenty of quality time together.
He added: "It's fun because in this business you are away from one another for long periods of time, so when you're on set together it's a brilliant thing, because you actually get to spend time together. Especially with this film, I got to spend time with her."

U2 won't release a new album until next year.
Although the band have performed live - appearing at The Oscars, The Golden Globes and on 'The Tonight Show Starring Jimmy Fallon' - and debuted two new tracks, 'Ordinary Love' and 'Invisible', they are still trying to perfect songs for their new album.
A source told Billboard magazine: "It seems to be taking longer for them to finish an album as they get older, but the great thing about U2 is that the whole of a record is always better than the sum of its parts.
"That magic that the band always seems to capture ... they have yet to capture it."
The album is being helmed by executive producer Danger Mouse and U2 - Bono, The Edge, Adam Clayton, and Larry Mullen - have scheduled further sessions with producers Ryan Tedder and Paul Epworth to complete the as-yet-untitled record.
Bono, 53, has previously said he is conscious of the band's age and having something to say on their 13th studio album.
He explained: "We're on the verge of irrelevance. You have to make stuff relevant to you and where you're at, make an honest account of what you're going through. If that's relevant to other people, great. But we don't know."
The singer also spoke about the inspiration behind the album, saying it goes back to when the group first got together in 1976.
He added: "We went back to why we wanted to be in a band in the first place. We were listening to the Ramones and Kraftwerk - you can hear both on 'Invisible'. It opened up a whole valve for me writing, it was like a damburst of sorts."

Justin Bieber's mother wants more kids.
The 20-year-old superstar's is the only child of Pattie Mallette - who raised him as a single parent after she and Justin's father split when he was 10 months old - but now she's beginning to get broody again
Pattie, 37, posted a picture of her holding a friend's baby and wrote: "A baby looks good on me eh? (Yep still Canadian). #iwantmorekids! (sic)"
It is not known if Pattie is dating anyone at the moment, although she has had a busy few months after Justin's behaviour started getting him into trouble. She flew to Panama for an emergency meeting with the 'Confident' singer alongside his manager, Scooter Braun, in January, after his arrest in Miami for allegedly having an expired license and resisting arrest. This came weeks after his home in Calabasas, California, was raided by the Los Angeles County Sheriff's Department, following the egging of neighbour's property. Days after his Panama break, Justin also flew to Toronto where he was charged with allegedly hitting a limo driver over the Christmas period.
Justin's father, Jeremy, has grown a strong bond with his son in recent years and was with him when he was arrested in Miami. After splitting from Pattie, he went on to marry Erin Bieber, with whom he has two children, Jazmyn, five, and Jaxon, four.

Dermot O'Leary is incredibly excited to be working with an astrophysicist for Channel 4's 'Live from Space' season.
'The X Factor' host will take viewers on an incredible journey around the world in 90 minutes, and while the series may be a dramatic change from his most famous role, Dermot says accepting the opportunity seemed like a no-brainer.
He told BANG Showbiz: "When I took the gig, a mate of mine was like, 'I didn't know you were curious about space?' And my take on it was, I don't know anyone who isn't curious about space? It just seems such a natural thing to do."
When Dermot was given the opportunity to watch the International Space Station pass over St Paul's Cathedral in London he found it almost impossible to comprehend the speed at which it was travelling.
He explained: "I just thought I wonder where it is now, and I thought in my head it'd be like Ipswich or the Netherlands and it was over the Bay of Bengal or somewhere like that. I mean it's extraordinary, it goes so many times faster than the speed of a bullet."
Channel 4's 'Live from Space' season kicks off next Wednesday (12.03.14) with two fascinating hour-long documentaries, 'Astronauts: Living in Space' and 'Astronauts: Houston We Have a Problem'. These shows aim to reveal life as it is for the people living and working on the International Space Station, the challenges they face and the day-to-day experiences they have.
The series of programmes will conclude on Sunday 16 March with 'Live from Space: Lap of the Planet', a major interactive television event centred around a live two-and-a-half hour broadcast from the ISS and Mission Control in Houston as the ISS completes an entire orbit of the earth.

Jamie Dornan says filming '50 Shades of Grey' has improved his walking.
The 31-year-old actor has been cast as sadomasochistic millionaire Christian Grey in the film adaptation of E L James' erotic novel and had to shoot a ballroom dancing scene which inadvertently made his day-to-day posture better.
He explained: "So basically, I've always had a complex with the way I walk. I've not always been told I've got a bad walk, but someone's always commented on my walk. It's always been a bit like, 'All right. That's how you walk?'
"My wife tried to help by making me lean back and then in 'Fifty Shades...' my character has to dance the foxtrot and the teacher said, 'Do it as though you are walking, heel to toe.'
"No one had ever told me that. I was always toe-to-more-toe! Now I just apply that every day, when I'm walking around."
Jamie - who is married to Amelia Warner - insists the movie will be a success even if just a small percent of those who read the book enjoy the film.
Talking on 'The Graham Norton Show', he said: "I mean, look, we're in a really powerful position that 90-plus million people have read the book so if like a third - I mean, a hundredth of those people - that's successful if they go see the film.
"It's a nice position to be in, but I have no idea what it's going to do."
Jamie stars opposite Dakota Johnson, who plays Christian's lover Anastasia Steele, in the movie.
