FOX Beat: John Stamos, Paget Brewster star in new show 'Grandfathered'

For a generation raised on 'TGIF,' John Stamos will always be one of the coolest uncles out there. In his new FOX comedy, 'Grandfathered,' he's trying out a new family role - grandpa!

The former Full House star plays Jimmy Martino, a life-long bachelor who was hit with a double bombshell - not only does he have a kid from a former relationship - that kid has a kid too!

Stamos, and co-star Paget Brewster, sat down with Kevin McCarthy to talk about the new show and how editors used throw-back pics of themselves to create photo props.

Stamos also takes a dig at his former co-stars Mary-Kate and Ashley Olsen from Full House who have declined to be a part of Fuller House, a Full House reboot.

"I have already made our twins sign a contract that if we ever do a reunion 25 years later they have to be in it," he said jokingly about the babies in 'Grandfathered.'

The new show priemeres September 29 on FOX. Get more details here:
