The 38-year-old singer-turned-fashion designer and her soccer star husband David Beckham are pulling out all the stops for the occasion, reported Contactmusic.
"Victoria's spending around 50,000 pounds. 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 special dyed-pink rabbits," a source said.
"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," it added.
The party was initially planned to be an intimate occasion but the plans rapidly escalated.
"The guests will be all the Hollywood parents and kids - Victoria often has playdates with other celeb mums such as Selma Blair and Nicole Richie. And obviously, her best friend, Harper's godmother Eva Longoria, will be there. Harper will get some amazing gifts," the source said.
