Don’t expect to see a grown up Michelle Tanner on Netflix’s Full House spin-off, Fuller House, because Mary-Kate and Ashely Olsen won’t commit.

The reboot, which John Stamos confirmed on Jimmy Kimmel Live in April, will star Candace Cameron Bure’s character, D.J Tanner. Both Andrea Barber (Kimmy Gibbler) and Jodie Sweetin (Stephanie Tanner) will return.

According to Fox411, sources say neither Olsen twin has agreed to return.

There was some confusion surrounding the twins and whether or not they were informed about the spin-off. They told Women’s Wear Daily the same month Netflix confirmed the show that they had “just found out” about it.

However, Stamos called that “bullsh-t” on Twitter.

“I guess we're going to talk to the creators and see what's happening,” Mary-Kate said at the time. Ashley added, “I ran into Bob [Saget] the other day and we didn’t even talk about it I'm going to call [Saget] and get his perspective."

It looks like they weren't convinced, though a cameo hasn't been ruled out just yet.
