Haute Event: Stephen Colletti from One Tree Hill Celebrates His Birthday at 1 OAK with Chelsea Kane

On Saturday night, “One Tree Hill” star Stephen Colletti headed to Sin City for a birthday celebration with his girlfriend and co-star Chelsea Kane at 1 OAK at the Mirage. The birthday boy began the night with dinner at Stack Restaurant & Bar before heading over to 1 OAK.

Seated in the same VIP booth that Fergie partied at on New Year’s Eve, just behind the DJ booth, Colletti and Kane danced the night away with a group of their friends including “One Tree Hill” creator Mark Schwahn.

Toward the end of the evening, Colletti was surprised when 1 OAK presented him with an extravagant Jean Phillippe birthday cake. The crew hung at the club until just after 3 a.m. before retreating to their suites.
