If anyone can help a girl get over her ex, it’s John Stamos.

Earlier this week, the 53-year-old actor visited Long Beach Memorial Hospital with his “Grandfathered” co-star, Josh Peck, and upon learning that a patient named Amanda had recently broken up with her boyfriend, he decided to give the guy a call.

“John, are you calling the ex-boyfriend?” Peck, 30, says while filming the scene that was posted to People. “This will go well. This is definitely going to go well.”

At first, Amanda’s ex, Jorge, doesn’t pick up, so Stamos decides to leave a voicemail. “Jorge, this is John Stamos,” he says into the phone. “I’m with Amanda, my new girlfriend. Apparently you guys broke up and I swooped right in. So, your loss, Jorge — your loss, because Amanda is a great gal.”

While he’s leaving the message, Jorge calls back and the “Fuller House” star speaks with him directly. “We heard you broke up with Amanda so we got our a**es down to the hospital and now we’re all dating and we don’t need you, Jorge,” Stamos quips as Amanda starts laughing. “I think you made a big mistake.”

Stamos then adds, “But it’s nice to meet you, pal.”

Yet another adorable moment to up Stamos’ heartthrob status.
