John Stamos Shares Photos from 'Groovy' 60th Birthday Party Featuring Family and Celebrity Friends

“It was a 60's party that was better than the actual ['60s]” the 'Full House' actor said of the star-studded celebration

John Stamos turned back time to celebrate his milestone birthday!

The Full House actor, who turned 60 last month, shared some photos from his 1960s-themed birthday party on Instagram Friday. The festivities, according to the actor, were "better" than the actual decade.

At the celebration held at The Canyon Agoura Hills in Agoura Hills, California, John was joined by his wife, Caitlin McHugh Stamos, and his son, William “Billy” Stamos, 5.

John's Scream Queens costars Glen Powell and Jamie Lee Curtis, as well as his Glee costar Chord Overstreet, also joined in the festivities. The group even posed for a photo with the birthday boy in their ‘60s-inspired outfits.

At the extravagant celebration, John, dressed in a very colorful ‘60s ensemble, danced the night away to a Beatles tribute band and some music from The Beach Boys.

He even took the stage himself at one point, standing onstage with a colorful guitar and mic in hand alongside his wife, who also sported a '60s-inspired outfit, and his young son.

The actor expressed his joy with a heartfelt speech, a source tells PEOPLE.

“This is my final birthday celebration! It's not about age, but because my life is so fulfilling that each day feels like a birthday," Stamos told partygoers, per the insider. "It's heartwarming that people want to celebrate me, but let’s wait till my 70th if it’s really necessary.”

During the "touching" speech, he also recounted "going home alone from his 50th birthday," the source said.

John's wife and sisters also gave speeches, as did his Full House costar Dave Coulier and Jeff Ross, according to the insider.

“It was a 60’s party that was better than the actual ['60s],” he concluded the post.

In another carousel from the fun-filled evening, John shared photos and videos of his “groovy” birthday cake from SusieCakes Bakery, which his son took a bite of before he could blow out the candles.

The bakery also provided the bash with some colorful, flower-covered cupcakes.

“We officially celebrated my 60th this past weekend!” John captioned the second post. “It was a night to remember surrounded by the people I love the most. I’m truly blessed.”

He continued, “Shoutout to @SusieCakesBakery for the groovy cake and endless supply of cupcakes. I may or may not be eating one as I type this 👀.”
