Boy, meet world!

Fred Savage -- the older brother of Boy Meets World actor Ben Savage -- announced Monday, Nov. 26, that he and his wife, Jennifer, had welcomed another little bundle of joy into their family.

The Wonder Years star, 36, shared the happy news on Twitter, with a photo of his newborn son's tiny hand. Below the snapshot, he wrote simply, "He's here."

The child is the third for the actor and his wife, Jennifer Lynn Stone. The couple have two other kids: son Oliver, 6, and daughter Lily, 4.

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."
