Mary Kate and Ashley Olsen have revealed that they won't be reprising their role as Michelle Tanner in the upcoming Full House spin-off.

“Although Ashley and Mary-Kate will not be a part of Fuller House, I know how much Full House has meant to them and they are still very much considered family," Robert L. Boyett, the show's executive producer, said in a statement to The Hollywood Reporter. "It has been exciting to see how they have built their professional careers, and I support their choice to focus on their fashion brands and various business endeavors. I appreciate their support and good wishes towards Fuller House."

John Stamos, who is also one of the show's producers, confirmed that the spin-off will happen back in April.

“We’ve been working on this for many, many years,” Stamos said on Jimmy Kimmel Live!. “The original creator Jeff Franklin and Bob Boyett and Tom Miller — we were trying to do some sort of spin-off and we wanted to give credit to the legacy. We didn’t want to just sort of throw it away. So Netflix came around and said ‘Let’s do 13 episodes.’”

The new version of the series, which will air on Netflix, will have a lot of the cast originals including Candace Cameron Bure as D.J., Jodie Sweetin as Stephanie, and Andrea Barber, will return as Kimmy Gibbler. Stamos will take on Uncle Jesse but on a guest role basis. Dave Coulier will also come back as Uncle Joey. Bob Saget, who plays Danny Tanner, and Lori Loughlin, who portrays Aunt Becky, are still in talks with the series.

After the Olsens' announcement, Stamos posted that he was "#heartbroken" on Twitter and but understood why they didn't want to come back.

He then posted another statement on Facebook.

Just so you reporters know - this is not a money gig for any of us- quite the opposite - we want to give the fans what...
