Megan Barton Hanson sent temperatures soaring as she attended the House Of Sims launch at the Dorsett City Hotel’s Jin Bo Law bar in London on Wednesday.
The former Love Island contestant, 29, put on a busty display in a tight black dress with a transparent panel which exposed her midriff.
It featured a slanted neckline and an asymmetrical hem, while she wore a black leather coat over the top.
Completing the look, Megan opted for a pair of black heels and went for a glamorous look with her make-up, including a bold red lip.
The new OnlyFans TV reality show gives an intimate insight into the lives of former The Only Way Is Essex star siblings Frankie, Demi, Chloe and Charlie Sims as they try to make it in Los Angeles, California.
The Sims family moved to LA in January to film the series and have promised it will be ‘the realest show you’re ever going to see’.
And the Sims sisters signed a deal last year worth £1million to become the new Kardashians on OnlyFans’ growing new TV venture.
The girls left ITVBe’s reality show TOWIE to pursue their new show House Of Sims which came out on Wednesday.
As part of the deal, the family will open OnlyFans accounts, but will feature Instagram-style pictures, with no explicit content.
House Of Sims has already racked the family £500,000 before it has even aired.
Chloe told MailOnline: ‘I get people will want to compare this to TOWIE, but this is a different concept; this will be a fly-on-the-wall insight into our lives as a family, currently calling it House of Sims as a working title.
‘It will be completely real, and we’re really excited to bring our viewers along on a big unfiltered adventure.
‘We’re proud to be The Sims, but being compared to the Kardashians all the time is a big compliment to us as a family. We want to see where this new show can take us and plan to go global.
