Fall Out Boy's member Patrick Stump is now a father. His wife Elisa Yao gave birth to their first child together, a baby boy, named Declan. The exciting news was shared by Ellen DeGeneres on her Twitter account on Thursday, October 16.

"It's a boy! Actually, it's a @FallOutBoy. Congrats @PatrickStump and welcome baby Declan! See y'all in 2 weeks!" the host of "The Ellen DeGeneres Show" wrote, attaching an adorable snap of baby Declan on the post. FoB's account also shared the same photo and wrote, "Welcome to the world the newest Fall Out Baby Declan."

Stump only announced that he and his wife were expecting a baby last month. "I'm about to have a kid or a tattoo. I'm like the snows of Siberia - just untouched. The band is in a crazy place right now because there's a lot of little kids running around," he said during an interview with 102.7 KIIS FM.

His bandmate Pete Wentz welcomed a son with girlfriend Meagan Camper in August. Wentz, who also has a son with ex-wife Ashlee Simpson, shared advice to Stump, "You can never have enough Kleenex and baby wipes."
