From Taylor Swift and Conor Kennedy to Jake Gyllenhaal and Minka Kelly, look back at the Hollywood's brief romances from this year
Amanda Seyfried, Josh Hartnett
The Les Miserables actress quietly began dating Hartnett in January. But sources told Us Weekly in June that the two were cooling down. "She's kind of a super clingy girlfriend and he doesn't want that," one Hartnett insider told Us Weekly. "He really likes his space and she wasn't happy about that." But the insider added, "They might hook up when she's back in town. He thinks she's fun and interesting."
