Paris Hilton

Paris Hilton and Doug Reinhardt seem to be moving at lightening speed, and we're loving it! Doug bought Paris a $25,000 diamond necklace the other day, and now sources tell us he's already introduced the heiress to his mother!

We snapped Paris, Doug and his lovely mom Kelly getting lunch at Longhi's in Maui yesterday afternoon, and afterwards the trio grabbed some ice cream and enjoyed a stroll around the lux shops in Wailea. Of course, Paris and Doug acted like newlyweds on their honeymoon, but we couldn't help but notice how chummy Paris and Doug's mama were!

Sources reveal exclusively to X17online that Kelly "adores" Paris, and everyone else in Doug's family thinks that she's the perfect match for him. After looking at hundreds of pics of the vacationing couple, I'd be inclined to agree!
