If there's one thing this family loves doing - it's riding bicycles!
Like seriously they can't get enough of it!
We're not sure which son it was, since we could only see the back of their head, but it was definitely either Alexander or Samuel.
Unless it was a third child that the actress had and didn't tell anyone about! Lolz!
