So long, Alexander. Hello, Michael.
The 28-year-old actress stepped out with director Michael Polish Wednesday night to catch Coldplay at the Samsung and AT&T Summer Krush concert at the Los Angeles Tennis Center at UCLA. The pair were incredibly close (even kissing!) throughout the show, according to a source, and Polish had his hands around her waist during several songs.
The identical twin brother of his sometime filmmaking collaborator Mark, Polish, 40, is currently directing Bosworth in Big Sur, the film adaptation of the novel by Jack Kerouac.
He is also the director of several films including The Astronaut Farmer and Twin Falls, Idaho, in which he also costarred with his brother.
