Lauren Conrad celebrated her 23rd birthday Saturday with her pals -- including Lauren "Lo" Bosworth -- and her actor-beau Kyle Howard, 30, at the Palazzo Resort Hotel Casino in Las Vegas. (Missing: Her pal Audrina Patridge and ex-beau Brody Jenner.)
Conrad's pals showed up before her and cheered as The Hills star entered the restaurant Lavo, where they dined on a specially prepared meal by Chef Ludo Lefebvre.
Her pals then surprised her with some Venetian masks, which they wore while eating.
Conrad's friends helped her blow out candles on the pale yellow birthday cake, which featured a green bow.
After dinner, they headed to club Tao (Conrad sat her on beau's Lap on the way) and danced in a private skybox. via
