NEW YORK (AP) - Fergie is a proud mother. A representative for the singer says she gave birth to 7-pound, 10-ounce Axl Jack Duhamel on Thursday. Axl Jack is Fergie and actor Josh Duhamel's first child. The 38-year-old singer married the 40-year-old actor in 2009. She officially changed her name from Stacy Ann Ferguson to Fergie Duhamel this month. Fergie is one-fourth of the Black Eyed Peas. She released her solo debut, "The Dutchess," in 2006. The album launched five big hits, including "Fergalicious" and "Big Girls Don't Cry." Duhamel has appeared on television shows including ABC's "All My Children" and in movies such as "Transformers."
