Ben Affleck is not riding solo.

The actor — whose marriage to Jennifer Lopez appears to be hanging by a thread — was photographed riding his motorcycle Wednesday in Los Angeles with his youngest child, Samuel, sitting behind him.

Affleck, 51, wore a navy blue T-shirt with jeans and white Nike sneakers, while his 12-year-old son donned a gray tee, bright blue joggers and gray tennis shoes.

The father-son duo made sure to sport helmets.
