Not to rub it in or anything, but we told you so. The new hotspot in Las Vegas is the Lily Bar & Lounge at Bellagio! 

 The upscale cocktail lounge drew a huge crowd — and some celebrity favorites!

Glee bad boy Mark Salling was on hand, as well as Cee Lo Green, Whitney Port and Eliza Dushku, who was joined by boyfriend Rick Fox.

The Midnight hour hosted a special performance by Robin Thicke, who surprised guests with a live set behind a mini grand piano, including his song “Lost Without You.”

The rest of the night’s music was provided by DJ Alexandra Richards.
