Paris and Marilyn Monroe Shop for Britney Spears

Paris Hilton brought her new pup, yes another new puppy, this one named Marilyn Monroe to shop with her at the Sydney Michelle boutique in Beverly Hills, Calif., this past Sunday.

The night before, the heiress helped pal Britney Spears celebrate her 26th birthday at a bash in Bel Air.

Hard to believe Brit is only 26, she has quite a log of interesting events in her life already!
