Jenna Dewan Tatum has signed on to host NBC's "World of Dance," a new series in which dancers compete for a grand prize of $1 million.

Judging the 10-episode series will be Derek Hough, NE-YO and Jennifer Lopez. Lopez also serves as executive producer on the show.

"'World of Dance' is a show by dancers for dancers," Lopez said in a statement.

"Jenna is the perfect addition to join NE-YO, Derek and me in our 'World of Dance' family. We are thrilled to have her."

"Jenna's background as a dancer, entertainer and actress make her the perfect choice to host and work alongside our three incredibly talented judges," added Meredith Ahr, president of Universal Television Alternative Studio at NBC Entertainment.

"We can't wait to get started and give these four superstars a chance to both articulate and demonstrate how transformational dance can be."

Tatum's screen credits include "Step Up," "Witches of East End," "American Horror Story: Asylum" and "Supergirl."
