After giving birth to twins last year, Mariah Carey gave her first performance as a mother Thursday night as part of Caesars' "Plot Your Escape" concert event. It was one of four shows performed simultaneously in separate cities.

"To be a part of this totally interactive experience was really a driving factor for me," Carey said, explaining why she chose this as her first onstage return to the public eye.

While Carey thrilled lucky New Yorkers, Lil Wayne tore it up in Los Angeles with Cee Lo Green, Maroon 5 played Chicago and Mary J. Blige kept it real in New Orleans.

"I'm so excited to be in New Orleans for the Total Rewards Concert," Blige said. "It's happening simultaneously all over the world and I'm just happy to be a part of it."

Lil Wayne offered this: "I appreciate this opportunity, I appreciate y'all and my name is Lil Wayne." Thanks, Weezy. We almost confused you with another phenomenal, incomparable dreadlocked rapper for a second.
