Hayden Panettiere is back on the market.

The Nashville star, 23, has split from Scotty McKnight, her boyfriend of more than a year, sources confirm to Us Weekly.

Insiders say that distance and different personalities played a part in the split but that the couple remain on good terms.

In October 2011, the Heroes alum opened up to Us about dating McKnight, who previously played for the New York Jets.

"I've always been that girl who has a lot of dude friends," she told Us. "I'm into sports, so Scotty and I have a lot in common."

The Scream 4 star does indeed have a sporty side. She and McKnight first stepped out together in June 2011, just weeks after she split from Ukrainian boxer Wladimir Klitschko, whom she dated for two years. But she insists she doesn't limit her dating pool to just athletes. (The actress also previously romanced actor Milo Ventimiglia and Hills star Stephen Colletti.)

"See, I date two athletes and then people assume I only like athletes, but if I dated all actors, people wouldn't say anything," Panettiere joked to Us in 2011. "But I like it. It's been a really cool thing because they're in similar circles, where they understand the schedule, the work ethic, the social aspect, but they're not exactly in your industry, so it works out well."
