Awww this is kinda cute!
Blac Chyna just happened to be in Vegas for Mariah Carey‘s Saturday night show, and whether it was planned or not, the audience sure was surprised when Mariah brought the VERY pregnant star on stage for some fun!
Rob Kardashian‘s love was seated on an ornate couch and blindfolded before getting a hot little lap dance from one of Carey’s dancers!
Afterwards she posed for pictures with Mariah as the music went on, too! Fun!!
Ch-ch-check out a few angles of the whole thing on video (below)!
LOLz! Looks fun!!
