Fall Out Boy? More like Fall Out Baby! Last night pop-punk fans were in for a real treat when Ellen DeGeneres announced that Patrick Stump's wife gave birth, posting an adorable photo of the tiny tot on Twitter. 

The daytime television host wrote, "It’s a boy! Actually, it’s a @FallOutBoy. Congrats @PatrickStump and welcome baby Declan! See y’all in 2 weeks!" The band's official account also shared in the excitement, writing, "Welcome to the world the newest Fall Out Baby Declan."

So, what's happening in two weeks? Could Declan make his television debut on Ellen? Will FOB perform their latest hit, "Immortals," from the upcoming Disney movie Big Hero 6 on the program? Will she give the little guy a kickass nickname? Little D? DeDe? Lan? Who knows! While you're guessing, make sure to peek at the cutie below!
