Simon Cowell has spoken.

The X Factor producer confirmed yesterday that Paulina Rubio and Kelly Rowland will come on board Season 3 of his Fox singing competition, replacing Britney Spears and L.A. Reid and joining him and Demi Lovato on the panel.

Saying he's "delighted" with the selections, Cowell added in a statement: “It just feels like the time to do something different.”

Rubio has judged Mexico's version of The Voice, while Rowland has done the same for the British X Factor.

Already in the taunting spirit that defines the show - much to the chagrin of many viewers - Rubio announced of her casting: “Simon, be careful what you wish for. Let’s see if you are ready to handle me, empieza la fiesta, amigo!”

What do you think of Rubio and Rowland as judges? Will you be tuning in to watch them this fall?
