Fergie made sure she was the center of attention at her 37th birthday soiree in Sin City this weekend.
The birthday girl pAArtied it up at 1 Oak wearing a very colorful and tropical Givenchy birds of paradise dress and black heels.
To finish off her look, Fergie let her wavy blonde locks down for the night and kept the makeup to a minimum.
Not bad for being 3 years shy of 40!
