Love changes everything — isn’t that what they say? And since Paris Hilton began seeing Benji Madden early in 2008, one of the world’s most famous (and infamous) party girls certainly has cut down a bit on her socializing.

"I mostly just hang out with my boyfriend and my sister," Paris admitted to OK! at the launch of the new Bandit hairband/extension in Malibu over the weekend. She also added her Simple Life co-star Nicole Richie and her fiancé, Benji’s twin brother Joel Madden to the mix. "Basically my family," she said.

"It’s cool because we are all dating twins," Paris added. "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."

So for someone notorious for her brief but intense relationships, how does Paris keep the romance fire stoked? "We’re best friends. We tell each other everything and we act like kids," she explained to OK!. "We go to the carnival and Disney World and Dave & Buster’s arcades all the time."

She also dropped this piece of love wisdom: "I think if you’re best friends with someone and you act like you’re a kid sometimes, your love will stay young."

Meanwhile, it’s been confirmed that Paris, who just finished shooting Paris Hilton’s My New BFF, is all set to film another season of the reality competition — this time in London.

"Because I had so much fun doing this one, I decided I need to find my new British BFF," she announced on her MySpace page. "Everyone knows I love L.A. But London, watch out."
