The former 'Celebrity Big Brother' star has announced her engagement to her businessman boyfriend by posting a photograph of her huge diamond ring last night (10.10.14) on Twitter this morning.
Luisa shared the happy news on Twitter with a picture of her left hand adorned with a large diamond ring, she then accompanied the photo with the tweet: "Feeling like the luckiest girl in the world. (sic)"
She later added a close-up photograph of her ring to the social media site, with the caption: "Thanks for all your lovely messages of congratulations on my engagement. Loving my @Boodles Ashoka cut ring (sic)"
Former 'The Apprentice' candidate Doctor Leah Totton, who appeared alongside Luisa during the ninth series of the BBC One show, also tweeted her congratulations to the star, as she wrote: "YAY! Huge congrats & much luv to u both (sic)"
Proving that they are still close friends, Luisa replied to Leah: "thanks bridesmaid (sic)"
The 27-year-old baking entrepreneur has been married once before, after she wed the businessman Oliver Zissman in 2009. The former couple have one daughter together called Dixie, who was born in 2010. The pair officially divorced in 2014.
Luisa has previously stated that her current boyfriend wants to stay out of the public eye. Talking to the Daily Star, she said: "I am in a relationship with someone who hates the media. So we've made a pact that I won't talk about that side of things."

Graham Norton used alcohol to help him "fit in".
The 51-year-old talk show host has admitted that he began drinking a lot of alcohol whilst he was studying drama at university, which triggered a life-long "love affair with the bottle".
Talking in the Daily Mail newspaper, Graham shared: "Drugs have, of course, crossed my path from time to time, but for me it has always been about the bottle.
"It helped me to fit in. Even now when I walk into some showbiz bash, I feel a rush of teenage fear and insecurity. Where's the waiter with the tray? Find him and then let the small talk begin!"
Referring to the time that he moved to a hippie commune in Los Angeles after he dropped out of university, he explained that he thought he became "very good" at covering up his drinking, despite waking up with "dried vomit" down his face.
He said: "I became very good at disguising my drinking and hangovers - or so I thought."
However, the 'Graham Norton Show' presenter did note that his drinking was now mostly under control and he doesn't let it interfere with his work on the BBC show.
He told the newspaper: "More than 30 years later, I still allow myself only one glass of wine on my chat show.
"Most weeks it never comes close to being finished and even back in the early Nineties, when I had drifted into stand-up comedy, doing the rounds in the pubs and clubs, I kept to the one-glass rule."

Taylor Swift and Lena Dunham bonded over their love of cosy evenings in.
The 'Shake It Off' hitmaker has formed a tight bond with the 'Girls' creator and star in recent years and also feels lucky to count Lorde and actress Jaime King among her close friends, as none of them enjoy going to bars or nightclubs.
She said: "We relate on different levels, but the one common thread between all of my friends is I can trust them. They aren't really much for going out to bars or clubs or anything. They're not really as interested in that and I'm not either, so it works out pretty well.
"It's really wonderful to have someone like Lena Dunham in my life. We have the same responsibility and the same pressure that's on you when you write every single word you end up performing.
"Ella - Lorde - and I geek out over music. She plays new songs she's heard, and we play each other new music we've written. Jaime King and I will sit around and talk and cook or just order in Chinese food.
"My group of friends are the most important thing to me right now. they are so fun and know me and like me for who I actually am."
The blonde beauty claims being single has helped her to get to know herself better.
She added to PEOPLE magazine: "I made the decision to spend time on my own and figure out who I am. When you're in love you tend to prioritise that other person's opinion and almost value it as much, if not more, than your own opinion. When you take the other person out of the scenario and you're walking through life on your own, you end up figuring out what you actually like without anyone else's input.
"I'm just happy to discover life's surprises as they come. I didn't used to be like that."

Tamara Ecclestone has threatened to "kill" internet trolls who are mean to her daughter.
The Formula 1 heiress has hit back at the internet bullies who have posted cruel messages aimed at her six-month-old daughter Sophia.
Talking about a particular incident in The Sun, Tamara said: "I posted a picture of Sophia on Instagram when she was three months old and someone wrote a really mean comment saying that she was overweight.
"She is purely breastfed and was just thriving. I went mental. Do not f*** with my child, or I will kill you!"
The 30-year-old brunette beauty also denied claims that she always looks glamorous as she explained that she doesn't use a nanny to help care for her daughter.
She told the newspaper: "People always think I'm glammed up because they see pictures of me at parties, but once I'm home, I'm straight into my tracksuit and putting on spot cream.
"I don't have a nanny either - I'm a completely hands-on mum. Sophia is my proudest achievement."
The millionairess admitted that she'd made her husband Jay Rutland sign a pre-nuptial agreement before they got married, but added that she thinks she would be happy without her big bank account.
She said: "As long as I have my husband, baby and family, I'm happy. Money can't buy you that."

Ricky Whittle was "too busy" for his ex-girlfriend Rumer Willis.
The former 'Hollyoaks' actor reportedly broke up with Rumer after his work schedule started to fill up after he landed a regular role on the US television show, 'The 100'.
According to The Sun newspaper, a source said: "Ricky and Rumer's relationship cooled recently.
"Amazingly, it was Ricky who was getting too busy with work and didn't have the time to spend with her any more. He'd often be filming 12 to 15 hours a day on 'The 100' in Canada, while she was in LA."
The insider then revealed that the 26-year-old actress has been fine with the split and is even reigniting things with a former flame.
The source told the newspaper: "Rumer's been fine about it and has barely mentioned him to friends.
"She is talking a lot to another ex, Jayson and going out with pals."
Ricky was rumoured to be close to Rumer's showbiz parents, although the source added that he while he'd got on famously with his girlfriend's mum, Demi Moore, he had been "terrified" to meet Rumer's dad, 'Die Hard' actor, Bruce Willis.
The insider shared: "It's a shame because he met Demi, who loved him. He was terrified of meeting Bruce."
Ricky had sparked speculation that he had split up with his 'House Bunny' beau after he tweeted a cryptic message in September.
He wrote: "It's better to have your heart broken by walking away than to have it break daily waiting for things to get better. (sic)"

Gwyneth Paltrow "could hardly speak" in front of the "handsome" Barack Obama.
The 'Glee' actress admitted to the President of the United States that she was completely awestruck by his good looks, as she attempted to hand him a microphone at a Democratic Fundraiser on Thursday (09.10.14).
According to the Daily Mail, the 42-year-old blonde beauty told President Barack Obama: "You're so handsome I can hardly speak properly.
"I am one of your biggest fans, if not the biggest."
Gwyneth was flirting with the President in front of a 200-strong audience who had paid a reported $25,000 to attend the event, which took place in the actress' L.A. mansion.
Barack later thanked Gwyneth and her two young children - Apple, 10, and Moses, eight - for their hospitality as he joked: "[Thanks] for letting us crash your house."
The President spoke at great length about the ebola crisis, as he told the crowd: "I want to assure everybody that the likelihood of an epidemic here in the United States is extraordinarily small.
"But there's a humanitarian crisis that's happening right now in West Africa where children, not much older, and in some cases younger than Apple and Moses, are dying on the streets alone."

Jamie Dornan claims he isn't very good at "selling himself" in auditions.
The 'Fifty Shades of Grey' actor has admitted that he struggles when trying out for a role because he doesn't think he comes across well.
Talking about his attempt to get a part on the television series, 'The Fall', Jamie said: "I'm not very good at auditions, I don't sell myself well. I didn't do a good audition for 'The Fall'. But the show's writer, Allan Cubitt, saw something in me. I think he had to work pretty hard to convince everyone else.
"'The Fall' changed my life - that's not an overstatement."
The 'Fall' writer admits he could see "potential" in the hunky star that went beyond his handsome face.
Allan told Britain's Vogue magazine: "I guess I saw his potential and didn't let anything else stand in my way. You only need to meet Jamie once to realise that he has a huge amount going for him beyond being physically attractive."
Jamie recently admitted shooting sex scenes with Dakota Johnson for 'Fifty Shades of Grey' was "strange work", but he had no problem getting intimate on camera.
He said: "I'm not really fearful of that stuff. It's just work. It's strange work, sure, but it's still work. I just get on with it."
He even revealed that his father had encouraged him to take on the role of Christian Grey, as he added: "[Dad] was all for it. I don't come from a cagey family. We're fairly liberal."

Ella Eyre is "too controlling" to be part of a group.
The 20-year-old singer admits being a solo artist suits her because all her lyrics are "really personal" and she would hate having to perform them with other people.
She said: "There's a video on YouTube of me singing 'Royals' with the three Rudimental singers but I'm too controlling to be in a girl group - all my songs are really personal to me, so I'd hate to share them."
The 'Comeback' singer thinks it is important to write from the heart and finds it helpful to channel any of her anger and "passion" into her songs.
She said: "People are just getting to know me as a solo artist and I think they want to listen to lyrics from the heart.
"I love singers like Adele, who is so true and real. When you're that angry and that passionate about a situation, when you've been f***ed over by someone that you care about, sometimes you just need to say it out loud."
Ella will release a new album next year and says it has "vulnerable moments" because she has exposed her lowest points in her songs.
She told Look magazine: "It's got vulnerable moments. Like everyone, I have down moments and points where I don't feel like I can cope, so I've written about that. But I don't like things to be too soft. Even if I'm making a sad point I like it to be quite poignant and direct."

Ben Affleck thinks Jennifer Garner has a "great a*s".
The 'Gone Girl' actor admires the fact his wife - with who he has children Violet, eight, Seraphina, five, and Samuel, two - chooses "thoughtful" movie roles rather than accepting light material where her looks are important.
He said: "I like that she picks smart, interesting movies to make, not goofy rom-coms where she shakes her a*s and stuff.
"Don't get me wrong, she's got a great a*s but I prefer that she's choosing to do more thoughtful films than that."
And the 42-year-old star feels "grateful" that his wife takes on the bulk of childcare in their household but is still able to find the time for her own career.
He added to Britain's Hello! magazine: "If a woman's at home she goes, 'Why aren't I out in the world working?' and if she's at work she's going, 'Why aren't I at home with the kids?' If she does half and half she doesn't feel she's properly serving either master.
"It's a very difficult choice that has to be made and Jen handles it frankly as well as anybody I know. I'm really grateful to her.
"She says, 'I'm going to have the primary responsibility for the kids, but I'm also going to find a way to do movies at the same time.' I like the way she does this."

Megan Fox will let her sons have sex with their girlfriends in her house when they are older.
The 28-year-old actress - who has kids Noah, two, and Bodhi, seven months, with husband Brian Austin Green - insists she isn't a strict mother and prefers to take a "liberal" approach to parenting.
She said: "In terms of being strict, I'm not at all. Like I'm going to be really liberal and lenient.
"If they want to have girlfriends they should bring them right on over because kids are going to do what kids do and I would rather they do it where they're safe at my house."
The 'Teenage Mutant Ninja Turtles' actress may not be very strict, but she won't let the youngsters use electronic devices or watch television as she thinks they are damaging to kids' health.
She said: "Sometimes I'm like a hippy granola parent in that I'm not giving them television or computers or cell phones because I think we live in an ADHD culture that's spurred on by constant use of electronics."
And Megan admits her laid-back attitude to parenting isn't shared with her husband.
She told Loaded magazine: "Brian's a little more uptight than I am with regards to cleanliness so we butt heads over things like I let the babies eat and throw food and drop stuff and splash in the bath because I feel I can clear it up and just let them be kids while they're kids and he's pulling his hair out.
"I won't let him correct it and it makes him crazy. He walks behind me, dusting after me wherever we go. We're opposites that way."

Peter Andre and Emily MacDonagh slept in separate rooms for a year after they started dating.
The couple - who have nine-month-old daughter Amelia together - were friends before embarking on a romantic relationship so didn't want to confuse the singer's children, Junior, nine, and Princess, seven, who he has with ex-wife Katie Price.
Peter said: "I remember going round for dinner and thinking she's beautiful, but she had her life and partner at the time.
"We were friends and two years later I thought, the person I should be with is right in front of me. I didn't know if she'd want to go out with me but I asked her dad if I could ask her out and it was instant.
"But we slept in separate rooms for a year - i didn't want the kids to get confused because they knew her as friends."
Despite their attempts to conceal the romance from Junior and Princess - who is nicknamed Bista - the kids weren't shocked when the pair revealed all.
Peter added: "I sat them down and said, 'Right kids, we need to have a talk. Me and Emily love each other. We've known each other for three years, I love her and I'll marry her one day.
"Bista rolled her eyes and Junior said, 'Dad we're not stupid'."
Despite being open about their relationship, the couple - who got engaged earlier this year - try not to be overly affectionate in front of the kids.
Peter said: "We still don't kiss in front of them now."
Emily added to Britain's OK! magazine: "We cuddle and we are more affectionate now though. They're the ones always saying, 'Dad give Emily a kiss.' "

Charlotte Riley wants to star in a movie version of 'Geordie Shore'.
The 'Peaky Blinders' actress - who is believed to have recently married partner and co-star Tom Hardy - is a huge fan of the MTV reality show and would love to play its star Charlotte Crosby in a movie of her life.
She said: "'Don't Tell the Bride' and 'Geordie Shore' back to back with salt and vinegar crisps, that's my night sorted.
"Maybe I could play Charlotte in 'Geordie Shore the Movie', she's my favourite."
Charlotte has enjoyed playing aristocratic horse trainer May Carlton in 'Peaky Blinders' but admits she longed for a more masculine appearance to be "in the cool gang".
She told Grazia magazine: "Because my character is always working with horses, there were a lot of trousers and culottes, which you didn't see many of the other women wearing.
"Filming the scene where May and Tommy meet, all the Peakies were standing to one side and I remember thinking, 'I want to be one of the lads! I want short back and sides and to have razor blades in my cap. I just want to be in the cool gang.' "
