Whatever happened to predictability? It’s no shocker that fashionistas Mary-Kate and Ashley Olsen were those “old familiar friends” who bailed on the cast reunion over the weekend for the 25th anniversary celebration of the popular nineties sitcom “Full House.”

Talk about a half empty house.

According to Entertainment Weekly, the Olsen twins who jointly played Michelle Tanner elected to be absent for the reunion of the show’s television debut in 1987 on Saturday in Los Angeles. The former cast listened to nineties nostalgia music, ate a cake modeled after the fictional family’s San Francisco home and read scenes from past episodes. Those in attendance for the reunion were: Candace Cameron Bure (D.J. Tanner), 36, Bob Saget (Danny Tanner), 56, John Stamos (Jesse Katsopolis), 49, Jodie Sweetin (Stephanie Tanner), 30, Lori Loughlin (Becky Katsopolis), 48, Andrea Barber (Kimmy Gibbler), 36, Dave Coulier (Joey Gladstone), 53, and Scott Weinger (Steve Hale), 36.

Guess the other set of twins, Blake and Dylan Tuomy-Wilhoit who played Uncle Jesse’s sons Nicky and Alex, didn’t get the reunion memo either. According to Blake’s Twitter, though, the duo do not keep in touch with the cast members anymore.

“sadly I was too young to make any strong relationships with any of the cast,” he tweeted. “I was sad when it was all over though!”

Meanwhile, the Olsen twins, who are now critically-acclaimed fashion designers, recently displayed their collections (The Row and Elizabeth & James) during New York Fashion Week earlier this month.

While the show may have extended throughout the 90’s long before social media was created, members of the cast took to Twitter to share their memories and thoughts about the reunion.

"Love my Full House family," Barber tweeted along with a photo of the cast now. In the middle of the reunion, she gave an updated that she “just danced to three NKOTB songs in a row with @candacecbure and @JohnStamos.”

And it wasn’t all about the cake and scene reading, but many of the members shared on Twitter that they had one too many drinks during the “Full House” reunion.

"my contribution to #FullHouse25Years a drunk gibbler, me and deej singing [New Kid on the Block's] step by step," Stamos tweeted with a video. "Full House rocks! Also, I may have had a couple drinks," Barber tweeted.

But what about a possible remake of the show? Back in August, Stamos told Vulture it is a strong possibility.

“The reunion had some movement, and then it was on hold,” he said. “But I think if we're going to do anything, we should do it while we're all still looking okay. We should get together and do reunion for TV Land or something. I don't know. It's 25 years this September since it first started airing, and no matter what I do, that's how people think of me. I've tried in the past to forget it and not be associated with it, but I've since learned to embrace it.”

One thing Stamos has not yet learned to embrace, though, is his infamous Uncle Jesse hair.

“I haven’t watched a full episode in, I’m sure, 20 to 25 years,” John told People. “If I see it on, I will flip. I mean, if [nothing other than] my hair being so gosh darn ridiculous. Didn’t anybody tell me that was going to haunt me years later?”
