Fergie and her husband Josh Duhamel has welcomed a baby boy into the world! Born on Aug. 29, the couple named their child Axl Jack Duhamel, and he's absolutely precious.

Duhamel, 40, and his Black Eyed Peas lady, 38, posted two photos of their baby boy on Tuesday on their individual Facebook pages.

"Axl Jack Duhamel Day 1 #paparazziyoucanleaveourhousenow," Duhamel wrote in the photo's caption.

Fergie posted a photo of Axl's second day on earth, showing her baby wearing huge earphones.

"Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillen," the singer wrote.

Little Axl's momma is a super-fan of Axl Rose from Guns N' Roses, which is where Fergie got her son's name.

"Fergie is a huge Guns 'N Roses fan - one of her career highlights has been performing and recording with Slash - so Axl makes perfect sense," a source told PerezHilton.com.

According to the gossip blogger, the couple joked about naming their baby North for a while, like Kim Kardashian and Kanye West.

"Coming from North Dakota, we were going to name it North, but you know, unfortunately, Kim and Kanye took that," Duhamel said jokingly.

Fergie's hubby also comment on her pregnancy before she gave birth, and confirmed he and his wife would like more children.

"[Fergie] looks like she's ready to go! She looks so damn cute. I'm going to miss seeing her walk around preggers. She's been really cool throughout this whole thing. It's been a delight actually, which is good because she's hopefully going to want another one soon," Duhamel said.

On Monday, the actor asked for privacy on Twitter when a fan asked if the couple would post photos of their newborn son.
