Lupita Nyong'o dances to Bruno Mars at star-studded Lancôme 80 party

With a star-studded roster of spokesmodels that includes Lily Collins, Lupita Nyong'o, Julia Roberts, Penelope Cruz and Kate Winslet, the Lancôme's Paris Couture Week bash was bound to be an exciting one. The cosmetic giant pulled out all the stops for its 80th birthday party on Tuesday night (July 7) as Kylie Minogue took the stage to perform her hits and attendees kept cool with lace fans.

Givenchy designer Ricardo Tisci shared a beautiful snap of Julia with her fan and Isabella

Actress Isabella Rossellini, one of the beauty brand's first ever faces, played emcee at the shindig, introducing each of the A-list ambassadors, which also included Canadian model Daria Werbowy and Alma Jodorowsky, one by one as guests clapped and cheered (by the time Julia was called up rest assured the crowd was in a state of pandemonium!). Isabella shared her excitement over the milestone and being on stage with a group of "strong, intelligent and joyful" women. Cue the pink confetti!

Pint-sized popstar Kylie, who was every inch the lady in red in a ruched scarlet strapless dress, launched a show-stopping performance with her hit song "Timebomb," and proceeded to sing a sultry, Marilyn Monroe-worthy version of "Happy Birthday" to Lancôme. Cue more pink confetti!
