IT was a night of dickie bows, designer gowns, chocolate and dancing -- and the Irish stars certainly let their hair down.
The party continued long after the final credits rolled for the 2014 Bafta Awards on Sunday night and there were plenty of familiar faces standing out in the crowd.
'12 Years a Slave' star Fassbender may have missed out on a gong for Best Supporting Actor, but he still had plenty to celebrate after the flick scooped the Best Film Award.
The star, looking dapper in a dickie bow and sporting a full beard, looked far from disappointed as he partied with his co-star and fellow nominee Lupita Nyongo, one of the best dressed on the night as she dazzled in a flowing, emerald green Dior gown.
Despite missing out on an award of her own, Lupita was all smiles as she threw her arms around Fassbender and posed for a "losers selfie" with her co-star and friend.
The Kenyan actress lost out in the Best Supporting Actress category to Jennifer Lawrence -- who starred in 'American Hustle'.
Meanwhile, she may not have been up for an award but it would not be a London party without Bray native Laura Whitmore in the mix who donned a mini blue YDE frock and showed off her toned pins in a pair of Jimmy Choo heels as she attended the Harvey Weinstein after-party.
She finished the look with a matching designer clutch and covered up in an Armani overcoat.
Laura (28) enjoyed the treats in the party's chocolate room as she rubbed shoulders with actor Eddie Redmayne, posed for photos with Irish thespian Allen Leech and singer Rita Ora, and even stood next to chat show host Oprah.
While Laura killed it in the style stakes, there were many others who did not rock it on the red carpet, according to Dublin fashion guru and 'This Morning' stylist Lisa Fitzpatrick who was far from impressed with UK singer Lilly Allen "who was noticed for all the wrong reasons".
The mum of two was also not a fan of 'The Fall' star Gillian Anderson's Balmain Haute Couture dress from William Vintage, describing it as "quite unflattering".
