Ready for take off! Fergie and Josh Duhamel celebrate son Axl's second birthday with aviation-themed bash

She wished her 'little maverick' a happy birthday on Instagram.

And in that fashion, Fergie and her husband Josh Duhamel, 42, appeared to take inspiration from aviation when they celebrated their son Axl's second birthday at the Chin Chin restaurant in Los Angeles' Brentwood area.

On Saturday, the couple were spotted at the eatery with their little one, who wore a pilot's jumpsuit and clutched a paper airplane.

The birthday boy was seen resting comfortably in his mother's arms just outside of the restaurant.

Fergie, 40, wore her honey blonde locks down in loose waves, and she also donned charcoal hued shorts that highlighted her lean legs and a pair of black lace-up ankle boots.

The Fergalicious hit-maker additionally wore circular sunglasses.
