Ryan Phillippe, 47, bonds with look-alike son Deacon, 18, as the duo spend the afternoon running errands in LA's Los Feliz neighborhood

Ryan Phillippe came to fame in the late 1990s

with starring roles in such films as I Know What

You Did Last Summer (1997) and Cruel Intentions (1999).

But the Delaware native looked to be more than happy to play

the role of doting dad to his look-alike son

Deacon during a one-on-one outing on Saturday afternoon.

The father-son duo made a few purchases while shopping at a meat market in the Los Feliz neighborhood of Los Angeles.

Phillippe kept things low-key in the fashion department

while dressed in gray sweatpants and a white long-sleeve shirt.
