This is what your 50's looks like when you're John Stamos.

Stamos -- who turns 52 on Aug. 19 -- celebrated his birthday over the weekend with a full house of his beloved co-stars.

His on-screen wife, Lori Loughlin, hosted a birthday BBQ at her pool and all the Fuller House favorites were in attendance. Bob Saget, Candace Cameron Bure and Dave Coulier showed up to celebrate, and the cast has never looked more comfortable together in the Instagram pics they posted.

"I'm not sayin who but someone in this picture poop'd in the pool. @dcoulier," Saget hilariously captioned a selfie of him, Stamos and Coulier, aka Danny, Jesse and Joey.

But the selfies didn't stop there! DJ Tanner also joined in on the photo fun! "One more for the road- #FullerHouse @bobsaget @johnstamos @melissacoulier @jodiesweetin @dcoulier @loriloughlin #Maks #leftshark," Cameron Bure wrote.

"Happy almost birthday," the 39-year-old actress tweeted. She also Instagrammed a video of Stamos blowing out birthday candles but later deleted the post. 

Also at the party was Jodie Sweetin, who captured an epic Frisbee moment between her on-screen uncles, Stamos and Coulier. "Frisbee time with @dcoulier and @johnstamos at @loriloughlin backyard BBQ!" the actress  who plays Stephanie Tanner wrote. "Fun Full House family day!"

Who has more fun than this on-screen family?!

ET saw just how close these co-stars really are when we chatted with Cameron Bure during Stamos' recent stint in rehab.

"I love him. We love him. And if this is what he needs to spend time to get things together we're all supportive and glad he's there and know that things will be good when he comes back," she said. "I support him, and we'll support him."

The 13-episode Fuller House will premiere on Netflix in 2016. The first episode will be a special one-hour reunion with the Tanner family.
