Paris Hilton has new best primate and shows it by planting a smacker

Paris Hilton has monkeyed around with some chimps in the past, but this is the first time she has been spotted locking lips with a real chimpanzee.

The socialite cuddled up to Bentley the chimpanzee at the opening of amusement park and nightclub Carnival in New York last night.

The 28-year-old animal lover was clearly in for a wild night as she wore a turquoise and purple leopard-print dress to the event.
