She had one heck of a 30th birthday, but Paris Hilton has fallen victim to a cake theft.

During the hotel heiress’ birthday bash in Hollywood, a party crasher that goes by the name “Paz” snuck into the fete and swiped the starlet’s $3200 cake.

Not too concerned with getting caught, “Paz” then bragged about the escapade on his Facebook page, writing, “I crashed Paris Hilton's Birthday Party and Accidentally Stole the Whole Cake.”

After being convinced by a pal to crash the party, he later wrote, "I woke up this morning with a birthday cake in my living room," wrote Paz. "It's big. It's red. It says 'Paris'.

The disappointed CEO of Viridian Spirits, which made the cake with Lucid absinthe, told press, "We had the cake designed especially for Paris with Lucid in the batter and a beautiful representation of Lucid's artwork on it, which she had requested to meet the Moulin Rouge theme of the party."
