Sophia Bush, and actor Jon Foster "broke up, like, a year ago"

"I am single," she said at the Switch Boutique Summer BBQ in L.A. "We are really good friends. We keep in touch, and we love each other to death."

The actress , "You can love somebody, and not be in love with them, and I think that was a really valuable lesson. We weren’t ready to get married, but it definitely doesn’t mean we don’t care about each other.”

These days, she told Us "the only two men I have time for are Barack Obama and my trainer. So those are my relationships."

"I love that he is the first politician who doesn’t feel like a politician," she said. "Senator Obama is the one person who's saying, 'We can change everything — but it can’t just be me, and it can’t just be you.'"
