What a little cutie!

Fergie and husband Josh Duhamel welcomed their newborn son Axl Jack over three weeks ago, and the proud parents are finally ready to show off their pride and joy!

The singer and the actor each posted their own sweet snapshots of their tiny boy on Instagram, and we can't get over how much he looks like his famous mommy!

"Axl Jack Duhamel Day 1 #paparazziyoucanleaveourhousenow," the Las Vegas star captioned one snapshot.

The Black Eyed Peas front woman posted another of her infant getting a hearing test with the caption, "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go."

We guarantee this is going to be a good looking, musically-inclined kid!
