Paris Hilton's Birthday Shopping For Birtney Spears

While she may have upset Britney Spears with her spotlight hogging ways, Paris Hilton was sure to take the time to pick out a present for her fellow paparazzi-lovin' pop tart.

The heiress spent Sunday afternoon hitting the shops in Beverly Hills at the Beverly Glen mall with her tiny Pomeranian pooch, aptly named Marilyn Monroe.

After stopping by a pet store, a stationers and the Sydney Michelle boutique, Paris finally called an end to the evening, making her way back home.

Back to Britney's birthday, according to recent reports, Britney was less impressed about Paris taking away her thunder on Saturday night. An onlooker told press: “Paris drank in the attention. Posing for the camera and eating it up.”

A source told the Daily Mirror that at one point, bodyguards had to pull the two apart, telling: “They were shouting at each other - it nearly ended in a punch-up.”

Despite the arguing, Paris found herself invited to the close-knit after-party held at the Four Seasons, with an insider explaining, “It was just one of those things that happen on nights out. There was no hard feelings, just drunken silliness.”
