The little guy entered the world at 7 pounds, 10 ounces and already has a kick-ass name: Axl Jack Duhamel, presumably in tribute to Axl Rose. As you may recall, former Guns N' Roses guitarist Slash joined Fergie onstage when the Black Eyed Peas played the 2011 Super Bowl, and she's covered "Paradise City" in the past. So she's clearly a GnR stan.
Speaking of names, Axl's mom has officially changed hers from Stacy Ann Ferguson to Fergie. Even stranger, Josh Duhamel only learned that fact when he read it online. Just FYI.
