Paris Hilton's new boyfriend has apparently bought her a new puppy.

The socialite was pictured kissing baseball player and star of The Hills Doug Reinhardt at her birthday party in Las Vegas, which took place at the weekend despite Paris turning 28 three weeks ago.

And it seems Doug gave her cause for celebration by giving her a Baby Teacup Pomeranian. "He probably got me more presents than any guy ever," the hotel heiress told People. "He's sweet."

Doug returned the favour, gushing: "She's a very amazing girl. She's the most beautiful girl on the planet. She's amazing, both inside and out."

Paris also sang her hit single Stars Are Blind for her new fella at the party at the Body English nightclub.

She wrote in her Heat column: "Everyone's been asking me about this 'mystery man' I've been pictured out and about with. His name's Doug Reinhardt, and I met him through mutual friends about a year ago in Los Angeles, at a place called Coco De Ville. So we've been friends since then. He's a very nice guy and we enjoy each other's company. That's all I'm saying."
