NEW YORK (AP) -- Simon Cowell has added former Destiny's Child singer Kelly Rowland and Latin artist Paulina Rubio to the cast of his competition show "The X Factor."

Rowland and Rubio will be on the show when it starts its third season on Fox this fall. They replace Britney Spears and record producer Antonio "L.A." Reid.

It's a reunion for Rowland and Cowell, although American audiences might not know that. She served as a judge for a season on the more successful British version of the music show.

In a news release Monday Rubio told Cowell to "be careful what you wish for." She said she wondered if the notoriously cranky judge would be ready to handle her.
