(CBS/AP) MALIBU, Calif. - Katherine Schwarzenegger, the eldest daughter of Arnold Schwarzenegger and Maria Shriver, says she fled to London after her parents separated, in part to escape a storm of unwanted attention.

The 21-year-old told Harper's Bazaar magazine she wanted to "go away and realize that it's not as big a deal in other places."

Shriver and the former California governor are in the midst of a divorce, after Arnold Schwarzenegger confirmed in May he fathered an out-of-wedlock child with a former housekeeper.

Katherine did not mention her now-teenaged half-brother in the interview, while discussing what she calls "definitely a difficult time."

She said she tries "not to care about what other people ... think," but that she's been consoled by Twitter messages from supporters.

"I really do believe everything happens for a reason," she added. "A lot of the time, it's hard to understand in the moment why things are happening, but I really do think that. I also like to think God doesn't really give you anything you can't handle."

Katherine told the magazine, "I've always been way closer to my mom."

"Even when I was little, I was glued to her all the time. I'm close to my dad, but they're totally different kinds of relationships," she added. "I talk to my mom about six times a day, and we constantly e-mail in between that. People say that I'm her twin. I guess it would be the Kennedy genes; my cheekbones are coming out. We'll be at the breakfast table and my mom will look over at me and say, 'I see them!'"
