There were drinks,  a cake and even a "New Kids On the Block" sing-a-long. The only thing missing when the "Full House" cast reunited to celebrate the 25th anniversary of the sitcom’s first airing was: The Olsen Twins!

Mary-Kate and Ashley Olsen didn’t manage to attend the party in Los Angeles on Saturday, but that didn’t mean the rest of the cast couldn’t have fun.

In a series of tweets and photos posted to her Twitter page, Andrea Barber shared the celebration with fans of the tv series that ran from 1987 to 1995.

The actress who played Kimmy Gibbler on the hit show posted a picture of herself with her former cast mates including Bob Saget, John Stamos, Candace Cameron Bure, Jodie Sweetin and Lori Loughlin.

Barber wrote: "Love my Full House family. Full heart."

The 36-year-old mom-of-two was obviously enjoying herself because she later wrote: "Full House rocks! Also, I may have had a couple of drinks."

And John Stamos has the evidence to prove it. The actor, who played heartthrob Jesse Katsopolis on the show, posted a video on his Twitter page of Bure and Barber singing "Step By Step" by New Kids On The Block.

Stamos wrote: "My contribution to #FullHouse25Years a drunk gibbler, me and deej singing step by step."

He can be heard warning the actresses: "I’m tweeting this s***."

But the hardcore "New Kids On The Block" fans weren’t done with singing that night. Barber later tweeted: "Off to the Sound of Music sing-a-long with @candacebure. Did I mention this night rocks?"

It appears that The Olsen Twins missed a great party!
