The Transformers actor shared an adorable picture of his tiny baby boy at the weekend, as the pair enjoyed some time together bonding over the football.
In the photo, Josh can been seen cuddled up to little Axl Jack, who is bundled up in a red blanket and staring directly at the camera as he sucks on a pacifier.

"Gonna catch some football with my little guy today," Josh, 40, wrote alongside the touching image.
The first-time dad and his wife Fergie, 38, haven’t been shy about posting photos of their son since his arrival on 29 August.
Just last week, the Black Eyed Peas singer shared a snap of Axl wearing a Sons of Anarchy beanie, writing, "Aaahh #BreakingBad is done!! Still learning valuable life lessons on #SonsOfAnarchy. #mommystvshowsrock."
The proud new parents first debuted their little boy on 17 September. "Axl Jack Duhamel Day 1. Life is good. #paparazziyoucanleaveourhousenow," Josh wrote on Facebook next to a picture of his son wrapped up in his hospital blanket.
Fergie later shared a picture of the little boy wearing a set of headphones. "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go."
"We can’t stop staring at him," Josh told E! News in September. "He's our little man – we made him together.
"There's something you can't really describe until you go through it. I think any parents out there would understand that."
