It’s been 18 years since Full House ended, but John Stamos’s former costars were among the friends who attended his 50th birthday bash in L.A. on Monday night.
Stamos’s TV wife (and pal) Lori Loughlin Tweeted a photo with Ashley Olsen (who was just 9 when the show ended), saying, “I had a great time hanging with Ashley last night! Such a beauty inside and out.”
Other stars in attendance at the Rat Pack-themed party at the Sunset Tower Hotel included Jeffrey Ross, who roasted the birthday boy, the Beach Boys, Glee’s Darren Criss and Tom Jones, who sang “It’s Not Unusual” to Stamos.
“I literally had the greatest night of my life last night,” Stamos Tweeted.
