Black Eyed Peas beauty Fergie and her husband, actor Josh Duhamel, have uploaded the first pictures of their first child together, Axl Jack.

The 'Big Girls Don't Cry' songstress took to her official Twitter page earlier this afternoon and posted a snapshot of the baby (shown below), who had been taken in for a hearing test. She wrote:

"Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillin."

Her husband then took to his social networking page and added another photograph (above left) along with the amusing caption: "Axl Jack Duhamel Day 1. Life is good :) #paparazziyoucanleaveourhousenow."

Axl Jack Duhamel was born on August 29 and weighed in at 7 lbs 10 oz, and Duhamel opened up about his name, telling the press: "Some people may not like it, some people may think it’s really cool, but we don’t really care."
