The celebs aren't having the best of weeks… especially in the lead up to Christmas.

Chris Martin arrived back in LA, after doing a number of appearances in Europe, to find out that he is being sued by a photographer who is claiming the singer ran him down with his Jeep. 

According to TMZ, photographer Richard Terry is stating that Chris intentionally hit him with his car while leaving a restaurant about a year ago. 

The incident was apparently caught on camera by another photographer who was standing across the street at the time.

Richard said that he was outside an Italian restaurant in Santa Monica when he saw Mr Martin and ew-wife Gwyneth Palthrow leaving and getting into a Jeep.

He then states that the Coldplay frontman deliberately turned his car's wheel abruptly to the right, hitting Mr Terry on the path.

In his lawsuit, the pap claims that Chris has "a significant history of repeated and ongoing violent acts against entertainment news people."

He also says that he was upset the rocker didn't stop to see if he was OK.
