Leighton Meester Wraps Up New Year's Week

Leighton Meester works out a Nina Ricci dress and Derek Lam shoes before performing a four-song set at Tao nightclub at The Venetian on Saturday night (January 2) in Las Vegas.

After the 22-year-old star’s performance, she headed to a sky box table in the moat overlooking the entire club where she celebrated her last night before heading back to the Gossip Girl set.

Earlier in the evening, she, her band, dancers and crew, feasted at LAVO. Leighton toasted her crew at dinner, thanking them all for joining her for the best week of her life (including performing at JustJared.com‘s New Year’s bash).

FYI: Leighton is wearing 291‘s “Tissue Jersey Scoopneck” top.
