It looks like John Stamos is a little bitter over the fact that Mary-Kate and Ashley Olsen chose not to reprise their role as Michelle Tanner in the upcoming Full House spinoff series, Fuller House.

Last night on The Tonight Show Starring Jimmy Fallon, the 52-year-old spoke about how great it's been to be reunited with his FH co-stars and managed to sneak in a little jab at the Olsen twins.

"It was just like a family reunion where some of the family members didn't show up," he said.

Earlier that day, the Grandfathered star spoke with ** Howard Stern** on Sirius XM about the whole debacle – even revealing that at one point, he offended the Olsen twins with a little white lie.

"I think there was some confusion," he said. "They said first I didn't ask them. And I didn't personally, but I was told they were asked [to join the show]. So, I had a knee-jerk reaction and said, 'Bulls–t, I did ask them.' And they got upset."

"So I did call and talked to Mary-Kate and explained what the show is going to be and told them I'd love for them to be on there and they decided not to, which I respect."

"They seemed very into it," he continued. "They just were afraid of acting. They don't consider themselves actresses. I said, 'Maybe you guys will just be in New York and we'll do a phone call or something,' and they were like, 'Let us think about it,' and it just wasn't for them, so…"

We have to admit, Fuller House won't be the same without the youngest Tanner sister around.
