Mariah Carey is working and playing hard in Las Vegas. During a break from her concert residency at Caesars Palace, the singer let loose at a Chippendales show starring Tyson Beckford. It wasn't your typical show with a star in the audience, though — at one point, Tyson escorted Mariah to the stage and gave her a performance she'll never forget. Mariah was sure to show her appreciation, tucking some cash into his pants. She later posted a photo of the experience on Instagram, writing, "Again, I've no idea how I got here!!" Watch it all go down in the video, above, then check out more hot stars with the right stuff for stripping.
