Turns out, her husband Nick Cannon's grandfather gave it his best shot.
"When some good old-school music came on, he was dancing up on the floor with one of Mariah's dancers," Cannon said on his 92.3 WXRM-FM radio show "Rollin with Nick Cannon" Monday morning. "My grandmother was all upset and ready to go home because my 75-year-old grandfather was dropping it like it was hot with some youngster."
Why the big dance party? Cannon, 29, and Carey, 40, renewed their vows at their Beverly Hills home Friday night in front of 100 guests. The couple first wed in surprise 2008 ceremony at Carey's Bahamian estate.
"My grandparents were crying because they didn't get a chance to come to the first or second one," said Cannon, "[so] a lot of family showed up."
Famous friends like Brett Ratner, Penny Marshall and photographer David LaChapelle also came to support the couple. And they brought gifts. Cannon was especially touched by LaChapelle's present: a dramatic portrait of Michael Jackson, taken before his death, dressed as an angel.
Said Cannon: "That meant a lot because I am a huge Michael Jackson fan. I always say Mike is the reason I am an entertainer."
"That gift was one of my favorite wedding gifts this weekend," he continued, "but I have to say my ultimate favorite was my wife accompanying me to the [Floyd Mayweather-Shane Mosley] fight in Las Vegas."
