'Hairspray' star Nikki Blonsky makes her nightclub debut tonight onstage at Feinstein's at the Loews Regency in Manhattan!

Nikki's new nightclub review, "Coming Home," runs Sept. 23 to Oct. 4 and features songs from Broadway, the Great American Songbook and pop classics by the likes of Bonnie Raitt and Melissa Etheridge, as well as selections from 'Hairspray.'

"I've always just sung songs that mean something to me," Nikki tells ET.

She plans to deliver "70 minutes of pure joy" and change it up with a variety of musical genres including jazz, rock, pop and even a little bit of opera.

"There definitely will be a song in there for each one of my family."
