Only a day after news broke that Joe Jonas is [article id="1599163"]dating his "Lovebug" video co-star[/article] Camilla Belle, Jonas' ex-girlfriend Taylor Swift said that the pop star left her for the actress, according to UsMagazine.com.

"They've been together since we broke up. That's why we broke up -- because he met her," Swift told the site at Wednesday's CMA Awards in Nashville. Swift was nominated for her single "Love Song," which she performed with help from Miley Cyrus' boyfriend, [article id="1597775"]Justin Gaston[/article], who played the part of Swift's love interest.

The singer, who told MTV News earlier this week that she [article id="1599032"]hasn't spoken to Jonas since their split[/article], said that most guys know what they're getting into when they date her. "I think they are starting to realize that if they are involved with me in any way, I will probably write a song about them," she said, adding, "You know what, if they don't want me to write bad songs about them, they shouldn't do bad things."

But Swift has already set her sights on some new guys. She's admitted that she has crushes on Chace Crawford and Justin Timberlake, whom she recently got to meet while visiting "The Ellen DeGeneres Show." "I just couldn't believe he was there!" Swift told the site. "He is absolutely my favorite person on the planet. For her to invite Justin Timberlake to come and be there to celebrate my album release week, it just says a lot about who Ellen is and how amazing she is."

The singer, who has no intention of leaving the music business anytime soon, admitted to "Extra" that she'd put down the guitar to shoot some scenes with Crawford. And what physical qualities is she looking for these days in a guy? "I think freckles are cute. ... I like freckles!" she told the show.
