Amid recent reports that the blond starlet and the True Blood hunk have called it quits...
Bosworth raised eyebrows when she hit Coldplay's Samsung AT&T Summer Krush concert in Los Angeles with Michael Polish, director and screenwriter of her upcoming flick Big Sur.
"During the show, they were very cuddly," a fellow concertgoer tells us. "She even introduced him to Lindsay Lohan."
We're told the two didn't go to any great lengths to hide that they were there together. "There were paparazzi outside and they didn't cover their faces or anything like that," says our source.
Bosworth and Skarsgård were first linked romantically while filming their flick Straw Dogs but have reportedly recently split. Skarsgård was in New York last night at a Rolling Stone magazine party at the Empire Hotel rooftop.
Sources tell us this wasn't the first time that Bosworth and Polish were out and about together recently. The two were spotted last week leaving the Chateau Marmont hotel in West Hollywood.
Reps for Bosworth and Polish did not immediately comment.
Polish and his identical twin brother Mark Polish made their mark in Hollywood over a decade ago with their drama Twin Falls Idaho.
Big Sur, a drama based on Jack Kerouac's novel of the same name, began filming in April and stars Bosworth alongside Josh Lucas and Balthazar Getty. Meanwhile, Bosworth and Skarsgård's flick Straw Dogs is set to hit theaters Sept. 16.
Other celebs at last night's concert were Channing Tatum and wife Jenna Dewan-Tatum, Breaking Bad star Aaron Paul, Camilla Belle and OneRepublic. Lohan tweeted "I love Coldplay!!!!!!!!!!!!!!!!!" along with a pic of her and little sis Ali's wristbands.
If only Bosworth were tweeting, too.
