Jessica Simpson

Jessica Simpson reportedly had to abandon her birthday plans on Tuesday after the paparazzi descended.

To celebrate her 27th birthday, Jessica had lunch with five friends at the Silver Spoon Beach house in Malibu and following in Lindsay Lohan's footsteps from last week, planned to throw a barbecue in the evening for more family and friends - but soon the beach outside the property was swarming with photographers.

A source close to Jessica told People magazine that they abandoned the beach house and relocated to her parents' house instead: "It was a private party and they wanted to keep it private."

"She was there with all of her closest friends and family. She had a great time. It was great night."

But her celebrations couldn't go on until too late into the night - she had to be up early to travel to an Army boot camp in Louisiana to prepare for her new film Major Movie Star. A source revealed: "She left for Shreveport. She's going to be in boot camp for two days to learn how to do Army drills and salute properly and that sort of thing."
