Jennifer Lopez Once Danced for New Kids on the Block  6/25/05

Jennifer Lopez once danced backup for 1990s boy band New Kids on the Block.

The Jenny From the Block singer, who also danced on classic American comedy sketch show In Living Color, flashed her fancy footwork for the band's numerous shows and concerts before finding fame.

Former band member Joey McIntyre says, "I danced with her back in the day! She was actually one of the New Kids on the Block dancers. She was a star back then, even though no one really knew it - but I did."

But given the choice, McIntyre's certain about who he'd rather share a dance with: "Angelina Jolie. No question. I'm not going to pass up a dance with her!"
