Sean Penn has been holed up at the Peninsula in Beverly Hills with new girlfriend Stacey Koplin, sources tell Page Six. The pair were spotted at breakfast on the hotel’s roof Tuesday morning. A spy told us, “She came up to the roof with wet hair, he looked totally frazzled. They ate and had coffee, but they were talking about something intense. They were deep in conversation the entire time.” They left together after an hour at 10 a.m. Just a month after ending his relationship with Scarlett Johansson, Penn has been repeatedly spotted with attractive brunette Koplin. They were seen on Malibu Beach and riding a jet ski together, as well as attending a friend’s party over July Fourth weekend. Meanwhile, Johansson cut a more lonely figure jogging in New York. Penn’s rep didn’t get back to us.
