It's been a big week for the Savage brothers. Also on Monday, younger sibling Ben announced that he and his Boy Meets World love interest Danielle Fishel had signed on to reprise their roles as Cory Matthews and Topanga Lawrence in a pilot for Girl Meets World, a spinoff of their beloved '90s series.

"I'm going to be a father! Well, on TV at least," the 32-year-old actor tweeted. "The Boy Meets World sequel is officially happening!"

The pilot is still in the early stages of development, but buzz is already building. On Wednesday, Rider Strong -- who played Cory's best friend, Shawn Hunter -- wrote on his website that although he's not currently involved with the new show, he's excited to watch what happens.

"It's the next generation," Strong, 32, said. "And I, for one, can't wait to see it evolve."
