The reality star made everyone stop and stare when she stepped through the door in this thigh-skimming little black dress that boasted cool kimono-style sleeves, a tie belt that nipped her in at the waist and classic high-neck detail.
Girl crush alert, girl crush alert!
Just when we thought she couldn't look any more glamorous, our attention turned to her oh-so-fancy footwear - the stunning pair of sparkly, studded Louboutin heels that Pete surprised her with during Sunday's episode of TOWIE.
Megan - who showed off her much shorter tresses - looked a million dollars in the snazzy shoes that lengthened her already perfect pins and accentuated her Majorca glow.
But back to that dress! Even though Megan is a bit of a designer fiend, she took to Instagram to reveal that she nabbed her LBD from none other than Miss Pap, but the best part is that it won't break the bank at £24.
That you'll have enough cash left over for some red soles, we can't promise...
We caught up with Megan at the swanky bash where she talked all things relationships and she also gave us the lowdown on her family's TOWIE debut!
"My family absolutely love Pete," she told Reveal.co.uk. "I feel like the last couple of weeks, the only person that's had my back on the show has been Pete [but my sister] is one of those girls that won't let anyone ever talk s**t to me!"
"Obviously I've built good relationships with people but as you grow up you realise who your true friends are and that's something I've learnt being in this industry," she added. "I've learnt who I can and can't trust but my sister will always have my back. It's good to have her on my side."
Megan and Pete looked perfectly loved up as they sipped on pink champagne and cocktails. The pair rubbed shoulders with Gogglebox's Scarlett Moffatt, former Geordie Shore babe Charlotte Crosby and TOWIE's Billie Faiers.
