sunglasses sun dress Katherine Schwarzenegger Maria Shriver

Maria Shriver and her daughter Katherine looked bright and radiant as they enjoyed a shopping trip at the posh Monique Lhuilier boutique in Beverly Hills, on Thursday.

The eldest daughter of Maria and Arnold Schwarzenegger recently sat down with Harper's Bazaar for a lavish photo shoot, and to promote her New York Times best-selling book, “Roch What You’ve Got”. She also dished about which one of her famous 'rents she's closest to, in light of her parent's recent divorce drama.

Katie revealed, “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. 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.”
