David and Victoria Beckham are reportedly planning a 50,000 "A-list event" for their daughter's first birthday.

Harper turns one next month, and the Beckhams are apparently organising an extravagant affair to ring in the milestone.

Victoria has spent weeks looking for the "perfect" outfit for Harper and is planning a girly day.

"There are no half measures in Hollywood - Victoria is pulling out the stops. It's going to be an A-list event," a source told British magazine Closer.

"She's spending around 50,000. The garden will be filled with big pink cuddly toys, pony rides, a bouncy castle, balloons and tons of cupcakes. It'll be totally pink. It sounds odd, but she's even hiring specially dyed pink rabbits!"

Victoria and David are eager to show off their newly decorated Hollywood home while celebrating Harper's big day. The insider added that the event will attract a host of famous faces.

"They haven't had a house party since they got their Beverly Hills mansion totally renovated, so they wanted a big celebration to show that off too," the source explained. "The guests will be all the Hollywood parents and kids - Victoria often has play dates with other celeb mums such as Selma Blair and Nicole Richie.

"And obviously Posh's best friend, Harper's godmother Eva Longoria, will be there. Harper will get some amazing gifts."

Victoria and David also have sons Brooklyn, Romeo and Cruz together.
