Actor John Stamos reacted to the announcement that Mary-Kate and Ashley Olsen would not be joining "Full House" reboot, tweeting that he was "#heartbroken".
The new 13-episode series, titled "Fuller House", will premiere next year, with Stamos, 51, producing and starring as his beloved character Uncle Jesse.
The show's executive producer Robert L. Boyett confirmed that the Olsens would not be joining most of their former castmates for the onscreen reunion.
"I understand they're in a different place and I wish them the best," Stamos tweeted on Friday.
"I promise you will not be disappointed with our reunion and spin off!!"
Stamos officially announced the rebooted series on April 20 during an appearance on Jimmy Kimmel Live.
"Fuller House" will begin with a one-hour reunion, before turning into a spin-off series featuring DJ Tanner (Candace Cameron-Bure) and her three children, along with her sister Stephanie (Jodie Sweetin) and neighbour Kimmy Gibbler (Andrea Barber).
