Joe Jonas celebrated his 25th birthday Saturday afternoon at Encore Beach Club at Encore Las Vegas with brother Nick Jonas, his girlfriend, Miss Universe Olivia Culpo, and 15 friends.
Festivities took place in a cabana overlooking the hot pool party scene below that included DJ sets by Matthew Koma and Martin Solveig. Immediately upon arriving, the brothers, both wearing muscle T-shirts, and a few pals lit up cigars. The group kept refreshed with beer, pitchers of mojitos and Grey Goose cocktails.
Nick and Olivia left together after about 90 minutes while newly single Joe and company partied on, observed checking out the sexy patrons dancing on the shower poles below and the 10 bikini-clad Maxim magazine models nearby.
