Sweet child o' theirs! Fergie and Josh Duhamel became first-time parents on Aug. 29 when the singer, 38, and actor, 40, welcomed son Axl Jack in Los Angeles. And now, nearly three weeks later, the Hollywood tot is ready for his closeup -- via social media, naturally!

On Tuesday, Sept. 17, both the Black Eyed Peas songstress and Safe Haven actor took to Facebook to reveal two adorable snapshots of their little boy, both of them apparently snapped on days one and two of Axl's life.

In Duhamel's photo, little Axl is comfortably swaddled in blankets and sleeps, pursing his lips and showing off red, chubby cheeks. "Axl Jack Duhamel Day 1," the caption reads. "Life is good ?#‎paparazziyoucanleaveourhousenow?."

Fergie's photo, taken one day later, is a nod to Axl's rock 'n roll roots, with the tyke wearing a set of headphones. "Axl Jack Duhamel. Day 2 of life. Hearing test complete," Fergie writes. "All systems go. ?#‎chillin?."

(The little boy was, after all, named after Guns 'n Roses frontman Axl Rose.)

The little guy weighed in at 7 lbs. 10 oz. at birth.
