Paris Hilton's young love
Paris Hilton and her boyfriend Benji Madden act like children to keep their "love young".
The socialite has revealed she enjoys visiting theme parks and amusement arcades with the Good Charlotte rocker because it ensures their relationship remains fun.
She said: "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 - claims being in a relationship means she has cut down on her socialising.
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.
Paris added to America's OK! magazine: "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."
