Paris Hilton's parents approve of Benji Madden romance

Paris Hilton's parents approve of their daughter's relationship with Good Charlotte rocker Benji Madden.

"This has honestly become the real thing," Kathy Hilton, 49, tells the Vegas Luxe Life blog. "It's a great love match, and I have a funny feeling it's going to go all the way, and we've already given it our approval."

Rick Hilton, 52, said of Madden, "He's the perfect example of 'don't judge a book by its cover.'

"He's polite, well mannered – even calls me sir. We love him like family already."

Paris and Benji returned to the U.S. after a month of touring Europe and South Africa with Madden's band. Since getting together in February, the couple have been inseparable; and wear rings on their engagement fingers of the other's initials.

"Their life has never been better," Kathy gushes. "We agree with Paris that he is an amazing guy... He's changed her life, and I really think she's genuinely in love for the first time."

Paris, 27, said on her blog recently, "I’ve been on tour with my boyfriend for almost a month now. We’ve been everywhere from South Africa to all around Europe. Its been so much fun. It has been an amazing and memorable experience."
