Bridesmaids and Pitch Perfect star Rebel looked lovely as she graced the red carpet in Los Angeles wearing a black knee-length shift dress.
Rebel teamed her dress with a pink-lined black cape, which complimented her pink heels.
However, the 29-year-old soon ditched the cape for something more flamboyant, as once the ceremony started, she swapped her demure ensemble for a racy attire.
Channeling a Victoria's Secret Angel with her very own large angel wings, Rebel wore a beaded bra top and tight leather-look trousers with the word 'THINK' emblazoned across it.
The actress and stand-up comedian wore the outfit as she graced the stage with her Pitch Perfect 2 co-stars.
Pitch Perfect 2 is set to return to our cinema screens next month, with Rebel as 'Fat Amy', Anna Kendrick as Beca Mitchell and Brittany Snow as Chloe Beale all making a return.
A trailer released two months ago showed the Barden Bellas setting their sights on the World Championships of a cappella.
