Axl Jack is ready for his close up! Three weeks after the arrival of their first child, proud parents Fergie and Josh Duhamel took to Instagram to introduce their son to the world. "Axl Jack Duhamel Day 1 Life is good :) #paparazziyoucanleaveourhousenow," the Safe Haven star posted on Sept. 17. Fergie shared a photo of her son wearing headphones on the same day. "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillin." So cute!
