Fox's two biggest sitcoms are about to collide.

Entertainment Weekly reports that Seth MacFarlane will lend his voice to NEXT fall's season 25 premiere of The Simpsons, stopping by his fellow Sunday night smash as Ben, a man Marge accidentally meets on an adult dating site.

“We thought we had a great part that he’d be perfect for, and it would be great to have him on our show, so it worked out just right,” The Simpsons producer Al Jean tells EW, adding of the two shows:

“There’s been a little rivalry. We’re both humor shows and we make jokes, but it’s always been friendly.”
