She got engaged to millionaire Andrew Collins during a romantic trip to Paris last month.

And Luisa Zissman was more than happy to flaunt her giant diamond sparkler - thought to be worth a cool ￡1.5 million - when she hit the town for the Adult Movie Awards on Saturday night.

The Apprentice 2013 star made sure her new bling was the centre of attention as she arrived at the bash, which was held at Spearmint Rhino gentleman's club in London.







Luisa coordinated her Ashoka cut ring with her jewel-encrusted Halter Prom Dresses, which featured silver trim around the waist and over her shoulders.

The outspoken reality star's stunning black dress also boasted optical illusion naked panels running down the sides and around the neck of the dress, giving the impression that she was wearing a plunging strapless number.

Luisa, who has kept his new romance largely under wraps until now, left her new fiancé at home as she let loose on wild party, also attended a large number of porn stars.

Luisa's divorce from business Oliver Zissman only completed in June, but she soon found love again with Andrew.

The Irish tycoon whisked the 27-year-old brunette off to the French capital for the weekend last month, surprising her with an eight-carat diamond ring during an intimate candlelit dinner overlooking the Eiffel Tower.

Share a photo of diamond sparkler on Twitter, Luisa gushed to her 533,000 followers: "Feeling like the luckiest girl in the world".

He told MailOnline: 'The Ashoka cut is synonymous with Boodles and a very rare incision in fact. In reality it is a modified emerald cut diamond with facets designed by Boodles themselves.

"Weighing in at a hefty eight carats, and at a very high spec color and clarity, I would appreciate this stunning ring worth ￡ 1.5million. A beautiful piece of jewelry."

The couple, who were first pictured together last October, began to see each other soon after Luisa separated from a fitness entrepreneur Oliver last year when she caught him cheating.





Celebrity Big Brother 2013 star - who has a four year old daughter, Dixie, her ex-husband - was clearly pleased with Andrew's choice of bling and wasted no time showing off engagement ring online.

She tweeted: "Thanks for all your lovely messages of congratulations on my engagement. Loving myBoodles Ashoka cut ring".

"The morning after the night before, on cloud 9 .... Now how do I take all these flowers home on Eurostar?!," She later added.

Luisa has kept tight-lipped about her media-shy boyfriend's identity, but recently opened up about her romance, hinting that she has finally found The One.





She said: "I guess you get to a point in life when you meet someone and think," Actually, I want to spend all my time with this person. "

"That was what happened to me, and I'm really happy. I feel for the first time in my adult life that I know who I am."

Luisa, who describes himself as having a body like Jessica Rabbit and a brain like Einstein, "first found fame as the runner-up in the ninth series, Lord Sugar's show The Apprentice.

She recently confessed she was bored for pretty boys and had chosen personality over looks with Andrew.

She told The Sun: 'Good-looking men are a*******s... and normally rich men are too ... It's all about their personality.

'My boyfriend now is lovely. He's good looking to me but I didn't pick him on that. He's kind and considerate and respectful.'
