The party was to celebrate the Pretty Little Thing collaboration with fashion and lifestyle influencer Nella Rose.
Molly-Mae could be seen flashing her abs as she headed to the event in brown tailored shorts and a matching crop top.
She covered up with a matching brown blazer, completing her look with a Louis Vuitton bag and knee-high brown boots.
Molly-Mae wore her long blonde locks down in loose curls, and opted for a glamorous palette of make-up, including a matte nude lip.
Molly-Mae was joined at the launch party by a number of her influencer pals – who also missed out on the Love Island launch show.
It comes as the ITV2 dating show returned to screens for the first time since last summer – much to the delight of fans.
The show featured a new twist, which saw the public play Cupid and vote for who coupled up with who.
Instead of the five lads and five ladies choosing who they want to couple up with as usual, the launch show saw fans getting to vote for each love match.
Boys Luca Bish, Dami Hope, Ikenna Ekwonna, Andrew Le Page and Liam Llewellyn were all happy with their lot.
The ITV2 show, hosted by Laura Whitmore, introduced a bombshell arrival in the form of Italian stallion Davide Sanclimenti, 27.
Indiyah Polack, who had already been matched up with Ikenna, said of Davide: “When I saw him I was very confused because I had no warning, but he is very good looking.” Model Tasha Ghouri added: “Straight away I was like, ‘Wow. Fit. Hot. Sexy. Hercules’.”
And paramedic Paige Thorne, from Swansea, gushed: “I’m done. I’m ready to get married. I’m ready to have babies.”
Davide, a business owner, was chuffed with what was ahead of him, saying: “When I walked into the villa, I saw all the girls and I’m really impressed, I’m not going to lie.”
