Mariah Carey Post-Baby Concert: Readies First Performance Since Birth of Twins

Now that she's whipped her post-baby body into shape, Mariah Carey is focusing on doing what she does best -- singing! The diva will hit the stage for her first live performance since giving birth to twins Monroe and Moroccan on April 30, 2011.

Mariah is set to return to the stage this week, headlining a free, intimate show at New York's Gotham Hall on Thursday (March 1) as part of the multi-city Plot Your Escape concert series.

Sean "Diddy" Combs will also hit the Gotham Hall stage, while Maroon 5 plans on playing a simultaneous concert in Chicago, Ill. New 'Dancing With the Stars' contestant Gavin DeGraw will be performing a set of his own in New Orleans. The Plot Your Escape's Los Angeles concert headliner has yet to be revealed.

While Mimi's first post-baby show is free, it is still quite exclusive. Only 50 tickets have been made available to the public for her concert -- but don't worry! You can catch Mariah's comeback in all its glory via live stream on March 1 at 9PM EST. The new mom's last live performances took place in late 2010, when she was in the earlier stages of her pregnancy, so we're sure fans are jonesing for some Mimi live!

Good luck, Mariah!
