Sean Penn's son Hopper was involved in an altercation with a photographer in Beverly Hills on Tuesday (26Mar13), according to U.S. reports.

The 19 year old was heading into an office building with his famous father when he was embroiled in an argument with a papparazzo.

According to E! Online, Hopper pushed the snapper, who caught the bust-up on camera.

Cops arrived at the scene and examined the footage, but all parties involved decided not to take the matter any further.

His famous father is no stranger to altercations with photographers himself - the Oscar winner was jailed in 1987 for attacking a snapper, and he has been in several fights with members of the paparazzi in subsequent years.

Hopper is Penn's son with ex-wife Robin Wright.
