That's how it is for Samantha Ronson, Lindsay Lohan's celebrity deejay girlfriend, and her two hipster siblings, music producer Mark and fashion designer Charlotte, who open up about their high-profile lives in the September issue of Harper's Bazaar, on sale Aug. 19.
When asked about la vida Lohan, a protective Ronson, 31 (who along with her older brother and twin sister dressed as the quirky title characters of the film The Royal Tenenbaums for the feature), says: "She's great. She's also 22 years old. I think people forget that."
"With the Internet the way it is, one second we're enemies, one second we're best friends, one second we're lovers, and then we're broken up," she continues.
Still, the DJ laughs off curiosity about her relationship with Lohan.
"Even the airport security guy in Canada asked me, 'So is it true?'" she says. "It's like, 'Oh, yeah, I'm telling you.' "
In an e-mail to Harper's, Lohan wrote, "I love the Ronsons. They're close to my ♥ and I respect all the work they do." But, she adds: "Samantha and my relationship is a private matter."
The Ronsons also share stories about their unconventional childhood. Mom, Ann Dexter-Jones, was a socialite and dad, Laurence Ronson, was a real-estate heir and band manager.
The two later divorced and Dexter-Jones remarried Mick Jones of Foreigner, leading to family events with Keith Richards and Daryl Hall of R&B duo Hall & Oates.
But Christmas with Pacino was a huge highlight. Recalls Samantha: "I had just watched Scarface, and I don't think I spoke."
Despite their glamorous upbringing, the Ronsons insist that their mother was far from lax.
Jokes Dexter-Jones: "I used to be nicknamed Mommy Dearest."
