Matthew Perry and Matt LeBlanc will be seeing a lot of each other this fall.

The former Friends co-stars are currently filming their respective shows on just steps away from each other on the CBS Radford lot in Studio City, California, and the pals spoke to ET about working in close proximity to each other. In fact, they’ve bumped into each other several times already!

“I’ve already seen Matty,” Perry, star of The Odd Couple, told ET’s Cameron Mathison at the CBS all-star Television Critics Association party on Wednesday. “I’ve already bumped into him twice!”

LeBlanc also recalled seeing his old friend on the lot, where he films his new CBS sitcom Man With a Plan -- just steps away from where Perry, 46, shoots Odd Couple.

“That’s great to see him there and it’s funny to see him on a lot and not run lines with him,” LeBlanc, 49, told ET. “It’s just strange for me.”

“It’s like, ‘What scene are you -- why are you out here? Oh no, no, no, you’re on a different show now!’ That was 20 years ago, nevermind!” he added.

At the panel for Man With a Plan on Wednesday afternoon, LeBlanc spoke of his friendship with Perry, with whom he starred on Friends for more than a decade.

"I can not see him for five years and then put me in a room with him and it'd be like I saw him yesterday," LeBlanc recalled. "We still [have a] short hand with one another. It's amazing. Ten years in a building with no windows with the door locked, we got to know each other pretty well."

Man With a Plan premieres Oct. 24 and The Odd Couple returns Oct. 17 on CBS.
