Britney SpearsBritney Spears has had two run-ins with the paparazzi in two days - one ending in a tirade from the star and the other with the police being called.

Earlier in the day on Sunday, Britney is thought to have asked the paparazzi to politely leave her alone, calling their stalking activities “illegal” but no heed was paid.

In the afternoon, Britney was driving in Beverly Hills when she pulled over to attend to son Sean as he was crying in the back of the car. When she tried to continue her journey, her path was blocked by a overweight video cameraman.

The star is said to have wound down her window and shouted: “You gonna get on a diet? Ever tried WeightWatchers, you fat f**k?”

As she started to pull away, she called: “Why don’t you run [after me]? You need to f**king jog, you f**king p***y.”

Then on Monday, she was ambushed as she tried to enter Lisa Kline’s clothing store on Robertson Boulevard. According to onlookers, Britney’s bodyguard tried to clear a path for the singer from the car to the store but photographers went “wild” as Britney tried to get through the scrum.

Witnesses told TMZ that the bodyguard jossled with the paparazzi, violently pushing each other around and staff within the store called the police. The situation had calmed down before the LAPD arrived but Britney received a police escort to the next shop on her itinerary.
