Axl's growing up!

Proud parents Josh Duhamel and Fergie brought their tow-headed toddler Axl to lunch in Brentwood on Thursday. Three's definitely company with this trio!

For the outing, Fergie wore ripped A Gold E jeans, an oversized scarf and a leather moto jacket. Too cool! Josh looked like he was taking it easy, wearing sweatpants and a zip-up fleece.

It looks like the 40-year-old and her husband of seven years were enjoying some low-key time together during their fast-paced life!

The pair had Axl on August 29, 2013 and it looks like Fergie is ready for more. When E! News asked the singer if she'd want a daughter, the sexy lady said, "of course, that would be amazing." We hope she gets her wish!
