Here's something you need to know. Or, at the very least, may want to know.

"I Need to Know" singer Marc Anthony will be serving as a celebrity mentor during The X Factor's upcoming season, a source confirms to E! News.

Jennifer Lopez's ex will be part of judge Simon Cowell's team and will offer up advice and guidance to the four contestants that comprise the group.

"Marc and Simon have known each other for a long time, and Marc's a huge worldwide-selling artist, so when The X Factor decided to film in Miami, it was perfect," the source tells us. "Marc really likes the idea of spotting new and young talent and he has strong opinions, so being a guest mentor with Simon and his category is perfect."

Fox, however, has no comment on this latest development.

The news of Anthony's involvement comes just days after it was reported that Justin Bieber would also be serving as a celebrity mentor on the show.
