Mila Kunis wants to "feel sexy" at her upcoming wedding.
The 31-year-old actress, who gave birth to daughter Wyatt Isabelle with fiancé Ashton Kutcher late last month, has reportedly started gently exercising and is sticking to an "extremely healthy" diet in a bid to regain her pre-pregnancy figure before they tie the knot next summer.
A source close to the 'Oz the Great and Powerful' star told gossip website RadarOnline.com: "She cannot wait to feel sexy again. She has started a very gentle cycle of postpartum yoga and going on walks with Wyatt until her doctors give her the green light to start intense workouts, which should be by the end of this month."
The insider added: "She has been such a sport about this whole pregnancy thing. But she is eating extremely healthy right now and will only allow natural foods into her body as well as the body of her daughter.
"Mila is a tiny girl and already looks like her old self again, but she really wants to get her banging body back in time for the wedding."
Mila and Ashton, 36, who got engaged earlier this year after less than two years of dating, are planning to get married next July.
Another source previously revealed: "[It] will be next July. They want to focus on their daughter first."

Sofia Vergara thinks Joe Manganiello is from "another species."
The 'Modern Family' star admits the 'Magic Mike' actor's physique is incredible and she feels very lucky she "gets to play" with him.
The 42-year-old actress told the 'Today' show: "To me, he's like another species. I look at him, and it's like I feel like I am like in the movie 'E.T.' Remember? When an alien lands ... and I'm the one who gets to play with it."
The Colombian star recently claimed she only started working out after she turned 40.
She said: "Everyone knows that I've never been into working out. I was always very happy with what I have. Then I hit 40 and I started seeing a softness everywhere on my body."
But the brunette beauty still has a very sweet tooth and is considering hypnosis to help her curb her addiction to sugary snacks.
She said: "I heard about someone in LA who got hypnotised so they wouldn't eat candy. I'm seriously looking into that because I'm obsessed [with candy]."
The couple started dating in July and former 'True Blood' hunk Joe, 37, previously revealed he had a huge crush on Sofia before they got together.

The character Steve Carell plays in 'Alexander and the Terrible, Horrible, No Good, Very Bad Day' is similar to his real-life self.
The 52-year-old actor said the part he performs in the new film is that of a 'fommy', a father whole also performs the function of a mother.
Asked to describe his on-screen character, Carell told the Guardian: "It's very complicated, but he's a father-mommy. It's basically a stay-at-home dad. It's a guy who hasn't accepted the reigns of father-motherhood, and parenthood. In the movie, I'm a fommy... in real life I'm kind of a fommy, too.
"The character is conflicted. He wants to be working again, and he also loves his family and enjoys taking care of his kids. So, there is the purity of that enjoyment coupled with that sense of ... him still striving to have a career. You know, that's something a lot of parents struggle with."
The new movie - which also features Jennifer Garner, Ed Oxenbould and Dylan Minnette - caused Carell, who has a daughter Elizabeth, 13, and a son John, 10, to dwell on his own experiences of fatherhood.
He reflected: "I got so much advice before I became a dad. Everyone was saying that I should read this book and you have to do this. You don't know until you become a dad and then you learn the role."

The couple, who got married in September 2012, made their first red carpet appearance together in New York City on Monday night (20.10.14) since announcing they are expecting their first child, and were extremely affectionate at the event.
A source told E! News: "Ryan was really sweet throughout the whole night. He was rubbing her shoulders, putting his arms around her and when Blake got up, he got up.
"They were smiling with each other and he kissed her on her cheek at one point. He also touched her belly."
The 27-year-old actress avoided alcohol at the bash and left early with her 37-year-old husband.
The insider said: "During the event, Blake raised her champagne glass to Denise Rich's toast to kick off the event, then promptly sat down without drinking it. She was seated with good friend, Lorraine Schwartz, and seemed to be having a nice time chatting to the other guests seated at her table. They didn't stay very long though and left before most of the performances began."
Another eyewitness also revealed the former 'Gossip Girl' actress couldn't resist giving Ryan "a good booty squeeze" on the red carpet.

The 58-year-old reality TV star, who split from the Olympic gold medallist last October after 23 years of marriage, claims she doesn't know if he has moved on with Ronda Kamihira.
Asked about reports her estranged husband is dating her former assistant, the 'Keeping Up with the Kardashians' star told Ryan Seacrest on his KIIS-FM radio show: "I have no idea what Bruce does in his personal time."
She added: "We've been apart for a long time."

Tina Fey wants Neil Patrick Harris to sing at the 2015 Oscars.
The 'This Is Where I Leave You' actress, who is set to host the Golden Globe Awards for the second time with close friend Amy Poehler in January, has no doubt the 'Gone Girl' actor will do a great job of presenting the prestigious rival ceremony in Los Angeles on February 22.
Asked if she had any advice for the 41-year-old actor, the former '30 Rock' star told E! News: "My advice, though, is sing! Sing because you can. Just sing the whole time. He can really sing."
Neil - who has previously hosted the Tonys and Emmy Awards - opened the Oscars in 2010 by performing a song and dance routine celebrating that year's hosts, Steve Martin and Alec Baldwin.
The actor recently said he wants the upcoming 87th annual ceremony to be a "classy" affair.
He said: "I don't want them to be super derivative of other shows that I've done. I don't want it to seem like I'm doing the same award hosting gig that I did on the Tonys, just now on a different stage ...
"I want to also just make sure that it's a classy event. I've always loved the Oscars and have great respect for its history, and the gowns, and the classiness of it."

Kesha reportedly swore under oath that Dr. Luke never assaulted her.
The 'Tik Tok' hitmaker, who has accused the music producer of sexually, physically, verbally and emotionally abusing her in a lawsuit, said they never had sexual relations and he never offered her drugs during a court deposition in 2011, but her lawyer, Mark Geragos, claims she was forced to lie at the time because the 41-year-old record label boss allegedly threatened her.
The blonde beauty was quizzed by lawyers about her relationship with Dr. Luke - real name Lukasz Gottwald - when they were both being sued by her former manager three years ago.
The court documents were unsealed on Tuesday morning (21.10.14) after Luke asked the judge to allow him to use the interview as evidence in their current court battle.
But the 27-year-old star's lawyer branded Luke's plans to use the deposition as evidence as "a pathetic attempt to once again blame the victim."
He also told gossip website TMZ.com: "Luke walked Kesha down the beach and threatened to destroy Kesha's life and the lives of her family if she didn't cover up his sexual assaults."
The 'Blow' singer, who sought treatment in rehab for an eating disorder in January, tried to resolve her issues with Dr. Luke privately before she decided to sue him last week in a bid to dissolve their contract.
Dr. Luke denies all of Kesha's allegations, and is suing her for breach of contract and defamation.

Cobie Smulders is expecting her second child.
The 'Avengers' actress and her actor husband, Taran Killam, are set to welcome their second child into the world next year.
A spokesperson for the couple, who already have daughter Shaelyn Cado, five, confirmed the happy news to PEOPLE.com.
The former 'How I Met Your Mother' star, 32, and Taran, also 32, celebrated their second anniversary last month, following their star-studded wedding at the Alisal Guest Ranch and Resort in Solvang, California in September 2012, where guests included Alyson Hannigan and Neil Patrick Harris.
The brunette beauty, who has two movies slated for release next year, 'Avengers: Age of Ultron' and Results', admitted in the past that motherhood was "the best."
Shortly after giving birth to Shaelyn, the 'Captain America: The Winter Soldier' star said: "I think I sleep an average of four hours a night now, so it's just like functioning on fumes sometimes. But it's the best."
Cobie and Taran got engaged in 2009 and although she kept details of his proposal private, she previously said it was very romantic.
Asked how he popped the question, she said: "That's personal, but it was very romantic, I'll tell you that much."

Jenny McCarthy would "love" for her son to be gay.
The former Playboy model, who has a 12-year-old child, Evan, with ex-husband John Mallory Asher, likes the idea of him wanting to shop and do her hair.
Asked how she would react if Evan were gay, the 41-year-old star said: "Oh my god, I would be so excited. We can shop! Do my hair!"
The blonde beauty, who recently married Donnie Wahlberg, says two of her male friends, who are getting married next year, helped her to raise Evan.
She told PrideSource: "They've pretty much been live-ins for the last five years of my life as a single mom when I was on the road raising Evan.
"Evan loves them dearly, and I love seeing through the eyes of an innocent child: He loves them for them and has no issue. It's wonderful."
Meanwhile, the former 'The View' co-host doesn't consider herself to be a feminist, even though she thinks men and women should be "adored and respected equally."
She said: "I've never been one of those people. I just haven't. I feel like female and males should be adored and respected equally, but I'm not going to try and go and make some kind of statement."
She added: "Even posing for Playboy, (people were like), 'You think that was a feminist move?' I don't know; I just needed to pay off college!"

David Arquette and Christina McLarty are exhausted and hormonal.
The couple, who have six-month-old son Charlie, sparked rumours they had ended their engagement when they were caught arguing with each other on camera over the weekend, but the 43-year-old actor says they're still in love and planning to get married.
The 'Scream' star told gossip website TMZ.com: "We are both hormonal and haven't slept in six months. Christina is still breastfeeding, I feel like I am."
David takes full responsibility for the argument and says their relationship is now back on track.
The duo, who got engaged three months ago, were spotted feuding following a romantic dinner at Craig's restaurant on Melrose Avenue in Los Angeles, and David was captured on camera shouting: "That's it, I can't take it any more. I'm done, I'm sorry. Just like the last guy. I'm just like him."
Former 'Entertainment Tonight' presenter Christina, 33, who seemed to be in tears, replied: "Stop David ... Come here, please!"
The couple have been dating on and off since 2011.
Christina was previously married to Joe Francis, while David was married to 'Friends' actress Courteney Cox, with whom he has 10-year-old daughter Coco, for 11 years until 2010.

Matthew McConaughey's three children have made him more compassionate and selfish.
The 44-year-old actor, who has sons Levi, six, and Livingston, 22-months, and daughter Vida, four, with wife Camila Alves, says they are his number one priority and have brought "clarity" to his life.
Asked about being a father, the 'Interstellar' star told the November issue of GQ magazine: "It's the one thing I've always wanted to be. Never is a man more of a man than when he is the father of a newborn. Whatever decisions you make in the first six months of becoming a father, double down on them. I mean, you're meeting the Courier. You're meeting the Shepherd, the Future Prince. You immediately have something you don't have to think about. You know what's important. Bam! And the clarity of that is like, 'Whew.' I definitely got more selfish. And at the same time, I think I got more compassionate, which don't always go together, you know?"
But the Oscar winner admits Brazilian model Camilla, 33, had to give him an ultimatum before he proposed and married her in 2012.
He said: "I had to get to the point where I saw it [getting married] as more than just the thing to do. I wanted to really want to. You know, I didn't want it to be a destination; the fun is that we're on the adventure together. And look, some of it had to do with her putting it on me. It took her going, 'C'mon, Big Boy, Mr. Easygoing-We'll- Get-to-It-When-We-Get-to-It. Either s**t or get off the pot.'"

Keira Knightley was "a goody two-shoes" when she was younger.
The 29-year-old actress claims she was a "boring" well-behaved child and never skipped school because she didn't want to upset her parents or teachers.
The 'Laggies' star said: "I didn't get into any [trouble]. That's the most boring thing in the entire world."
She added: "I was absolutely a goody two-shoes."
Discussing what she was like when she was 16, she told her co-star Sam Rockwell in a game of 20 questions on E! News: "I think I was pretty neurotic."
Asked if she has changed, she replied: "No, not that much."
The British actress, who married the Klaxons star James Righton in the south of France in May 2013, would love to hide out in a vineyard if she could run away from her life for a week.
She said: "I'd go to a vineyard, probably in Burgundy, and I'd sit there and drink an awful lot of really good wine."
Keira recently admitted she isn't worried about celebrating her 30th birthday next March because she no longer cares what people think about her.
She said: "I'm not actually worried about turning 30. Because, honestly, my early twenties were not much fun. Then after 25, things just got better and better.
"Maybe you stop caring as much about where you should be going and what other people think - which is all the s**t that makes you very unhappy early on."
