Pop diva Mariah Carey has performed her first live show since giving birth to twins last year. The star took part in the "Plot Your Escape" concert on Thursday, a series of live concerts from New York City, Los Angeles, Chicago and New Orleans that are streamed online for free.

Playing her first live show since late 2010, the 41-year-old singer sang several of her hits such as "Hero", "Touch My Body", and "We Belong Together" in New York. Rapper Lil Wayne and R&B star Cee Lo Green (of the NBC singing contest series "The Voice,") also performed in Los Angeles.

Rock band Maroon 5, and pop-'n'-soul singer Sara Bareil-les performed in Chicago. R&B singer Mary J. Blige and rock singer Gavin DeGraw, who was recently revealed to be a celebrity contestant on ABC's "Dancing With the Stars," sang in New Orleans. The "Plot Your Escape" gig is part of a four-show concert-series, which is sponsored by Caesars Entertainment's "Escape to Total Rewards" program and is streamed online.
