It may have been more than three decades since John Stamos and Dave Coulier burst onto our TV screens, but the IRL pals are still close. The Full Houseactors posed for a mirror selfie, which John shared on October 15. “Two dudes,” he captioned the shirtless snap, adding, “Oh crap- I just noticed my bellybutton. Ha.” It seems the photo was a throwback, as John included the hashtag, “flashback Friday.”
