Paris Hilton & Benji Madden Keep Their Love "Young"

Paris Hilton and her boyfriend Benji Madden visit theme parks and amusement arcades in order to keep their "love young."

The socialite, 27, says she and Good Charlotte rocker Benji, 29, act like children because it ensures their relationship remains fun.

She explains, "I think if you're best friends with someone and you act like you're a kid sometimes, your love will stay young.

"We tell each other everything and we act like kids. We go to the carnival and Disney World and Dave and Buster's arcades all the time."

Paris -- who is renowned for her wild partying -- also claims being in a relationship means she has cut down on her socializing.

Instead of spending time in nightclubs, the star prefers to enjoy quiet nights in with her sister Nicky and best friend Nicole Richie, who is engaged to Benji's twin brother Joel.

She said, "It's cool because we are all dating twins. Even my sister is dating a twin - David Katzenberg is a twin. My cousin is dating an identical twin. So, we all date twins and we all hang out. It's pretty interesting."
