WATCHJohn Stamos Shares Throwback Video of Himself With ‘Full House’ Costars Mary-Kate and Ashley Olsen

Have mercy!

John Stamos took to Instagram on Sunday, Feb. 21 to share an adorable throwback video of himself with his former Full House costars Mary-Kate Olsen and Ashley Olsen — and it is so cute to see the Tanner girls cuddling up to Uncle Jesse in the behind-the-scenes clip!

"#StamosHomeMovies," the 52-year-old actor captioned the video of the adorable twins — who were just three-years-old at the time! — giving him a hug on location in Hawaii back in August 1989.
