Aaron looked dapper in a navy suit, which he paired with a white button down and a black tie. The 34-year-old also posted a picture of his buzzed-cut via Instagram on Sunday.
"Just hanging out with babies on their birthday. Happy one year you beautiful boy you. So happy for you @laurenbeaney and @dorian_beaney for this little guy. #Beaneybaby," he captioned the shot of him and the little guy.
The haircut's definitely a big change for the "Need For Speed" star -- do you like the look?
