Yesterday's news that Netflix has commissioned a spinoff of "Full House" was accompanied by a love-fest, from fans and the show's cast members. But two prominent stars are "shocked" that it's actually happening -- and that nobody told them about it!

Mary-Kate and Ashley Olsen -- who played precocious youngest daughter, Michelle Tanner -- told Women's Wear Daily that the spinoff was just as much news to them as the rest of the world.

"We just found out about it today," Mary-Kate said. "I guess we're going to talk to the creators and see what's happening."

"I ran into Bob [Saget] the other day and we didn't even talk about it," added Ashley. Nor did they hear from John Stamos, who is producing the show and plans to guest star.

The spinoff, titled "Fuller House," will star Candace Cameron Bure, Jodie Sweetin, and Andrea Barber, who will reprise their original roles in a set-up very similar to the original comedy. So, two of the Tanner sisters are in - so where's Michelle? The Olsens want to know, too!

Ashley said, "I'm going to call [Saget] and get his perspective."
