Fox has ordered two new seasons of the show, which just premiered its sixth season on October 5, reported Ace Showbiz.
"Six seasons in, the Belchers have become one of America's most beloved TV families, and we are so happy to keep them in the fold for another two seasons," said Fox Broadcasting Co Entertainment president David Madden when announcing the renewal on Wednesday.
The Emmy-winning animated series will air its 100th episode in spring 2016.
