Britney Spears calls the cops on paparazzi

Lately troubled Britney Spears has been stirring up trouble everywhere; but this time the police had to be called in.

The troubled singer had to make a visit to an hospital for her new puppy, London. Britney Spears and her assistant/cousin, Alli Sims, left her Beverly Hills home on Friday around 1 p.m. cradling her Yorkshire Terrier puppy.

Reports say that Spears seemed quite upset as she got to the hospital. Spears handed the puppy to Sims, who took it inside, while she waited in the car with her two sons. Spears reported;y became frustrated with the paparazzi while she was waiting and called the police for help.

Britney was finally able to move when the road was cleared. Us Weekly magazine confirmed that the puppy was treated by a veterinarian, and Sims insisted that the dog only went in for a checkup.

Spears was recently divorced from Kevin Federline. The pair share joint custody of their sons, but Federline reportedly wants sole custody because he believes that Spears isn't fit to care for the children.
