Taylor Swift TaylorJoeJonasbreakup.jpgTaylor Swift is opening up about her break-up with Joe Jonas.

On Wednesday morning's "On-Air with Ryan Seacrest" Taylor confirmed that the two had been dating and the split had been painful.

Ryan asked Taylor if she'd ever "really been deeply hurt by someone."

"Once," the singer said referring to her break-up with the Jonas brother.

"It's tough, and it's been tough. And you just have to realize that someday you'll find someone that's right for you," Taylor said.

Swift said she wrote the song "Forever and Always" on her new album "Fearless" about the break-up.

"I write about my life," she said, "it helps me that I can talk about what happened and just get it out of my system."

While Taylor didn't say exactly what led to the break-up, she said that Joe Jonas wasn't allowed to be seen in public with her because The Jonas Brother's management thought it would hurt Joe's heartthrob image to have a girlfriend.
