Can you blame him? Look at how darling little blonde Amanda is with her short curly 'do and white collared dress!
The adorable black and white Instagram pic, which the 27-year-old actress added to her account on Saturday, Oct. 12, shows the actor smirking at Amanda.
She captioned the humorous shot, "I used to be a child."
Justin is the third "face" in the photo, perfectly accompanying (and fitting in the frame!) the two shots of kid Amanda posing.
In one pic, she is grinning, proudly displaying her two front teeth. The other is more serious, shown in profile with her mouth slightly open.
What a cutie!
Maybe current-day Amanda is thinking about what her brood would look like with Justin?
The Lovelace star told Glamour in 2012 "I think about kids all the time. I feel like the next person I commit to, that's going to be the guy who I'm going to have kids with. That's in my crazy female brain. So that's why I'm like, 'I can't commit.'"
