Misty Copeland, the first African-American principal ballerina in the history of the American Ballet Theatre, will join NBC’s Jennifer Lopez-helmed series World of Dance as a guest judge. Copeland will sit alongside Lopez, Derek Hough, Ne-Yo and host/mentor Jenna Dewan Tatum on the July 18 and July 25 episodes of the highly rated competition series.

The competition consists of five rounds: Qualifiers, Duels, The Cut, Divisional Final and the World Final. Copeland will judge round three, The Cut, in which the dancers will face the most intense cut of the season. More than half of the acts will be sent home, with only the top two from each division moving on to the Division Final. Judge and executive producer Lopez said of the ballerina joining the series, “When judging the best of the best, we knew we needed an all-star guest judge with passion and credibility to mentor these incredible dancers. Misty Copeland is at the top of her game, and we are so honored that she was able to lend her expertise and experience to the World of Dance stage.”

In partnership with pre-eminent global dance brand World of Dance, the series brings elite dancers from around the globe together to compete in epic battles of artistry, precision and athleticism for the $1 million grand prize. Solo acts compete against duos and crews in an unlimited variety of dance, including hip-hop, popping, locking, tap, ballet, break dancing, ballroom and stomping.

World of Dance airs Tuesdays at 10 p.m. ET on NBC.
