Mariah Carey's Vegas show got a very special guest this weekend.
Mariah Carey has been doing a regular show at The Collosseum in Vegas, performing a collection of hits called #1 To Infinity. One of the many Billboard Hot 100 #1s she's been performing is "Touch My Body," a playful R&B cut co-written by The-Dream. AT her most recent performance, she incorporated yet another R&B force into the show, but he didn't contribute any vocals. John Legend came through with his wife Chrissy Teigen, to watch the show, but ended up blindfolded in the midst of the "Body" performance. You'll have to watch to see exactly what goes down, but it certainly wasn't anything Teigen didn't approve of, who cheered excitedly from the crowd.
