Safe Haven actor Josh shared a photo of his 11-week-old son behind the wheel of the mini car yesterday (18 November).
Axl, who is dressed in a navy blue top, doesn't look fazed by the toy motor, as he rests his hand on one of the gears.
Posting the snap to Instagram, 41-year-old Josh joked: "Babies, start your engines!" Could Axl be a future Formula One racing champ?!
Fergie and Josh welcomed Axl on 29 August and have been totally besotted with their first child. Josh recently told E! News that the couple are "obsessed" with Axl. "We can't stop staring at him," he continued. "He's our little man, we made him together."
The couple have released a few photos of their little boy and each one is just as cute. Last week, Black Eyed Peas star Fergie shared an adorable photo of Axl grinning as a present for Josh's birthday.
