Mariah Carey is one busy mama! The proud parent of Dem Babies is gearing up for her first performance since their birth at a private New York City concert. Only 50 tickets have been released to the public, but fret not, lambs! She’s streaming her show online.

The Boombox reports that Mimi’s special, exclusive set will take place at New York City’s Gotham Hall tonight. It’s free and intimate — and it’s part of a larger network of shows. The concert is part of the Plot Your Escape Concert Series. Diddy will share the stage with Mimi at Gotham Hall.

Other artists on board with the project include Gavin DeGraw, who will perform in New Orleans, while Maroon 5 will hit the stage at the same time in Chicago.

Mimi’s last performance was at the end of 2010, so this is a big deal for the newly svelte diva. You can catch her performance on live stream tonight at 9PM ET.
