Tuesday night Brooklyn Decker and Angela Kinsey got up on stage to perform their rendition of Britney Spears’ “Baby One More Time” for UNICEF‘s Playlist with the A-List fundraiser in New York.
They weren’t the only ones who came out to show off their karaoke skills. To name a few, Ne-Yo sang “September,” Emmanuelle Chriqui got down with “Hit me With Your Best Shot” and “Jack Black put on a scary mask for”War Pig’s”. Olivia Munn, Adrian Grenier and even a very pregnant Alyssa Milano were in the audience cheering their friends along.
