John Mayer arrived at the Hard Rock Hotel & Casino in Las Vegas on Tuesday, spent time on the casino floor and had the hotel staff in stitches with his famous sense of humor (Photo credit: Cody Boor / Hard Rock Hotel & Casino). On New Year’s Eve, he dined at Nobu with friends, rocked The Joint with his blues band John Mayer Trio – during which he toasted his father who was in the audience, brought friends Bob Saget, Jeff Ross and James Smith on stage for some laughs before leading the New Year’s Eve countdown. He then celebrated at Vanity afterwards with friends/family.
Also seen partying with friends at Vanity Nightclub was Nicky Hilton. The heiress hung out in the DJ booth with DJ Vice and friend Jon Alagem, rocking out to the music.
