Is Miley Cyrus over Nick Jonas or not?

JustJared reports that during a concert in Lisbon, Portugal on Saturday, the 17-year-old Cyrus played a song, "Full Circle," and explained its meaning:

"It's about two people," she said. "They're always gonna come back together no matter what anyone says or the bad people that try to keep you apart. Surprise surprise, it's about a Jonas didn't hear that."

The sad chorus goes: "I try to run but I keep on coming back full circle and I can’t jump the track, can't let you go."

Cyrus and Jonas, also 17,  broke up at the end of 2007, and she told Seventeen in 2008 that she "bawled for a month straight" and dyed her hair black in the aftermath. In June of last year, following her breakup with Justin Gaston, she said that she and Jonas "definitely reconnected. We don't know what's going to happen in the future, but right now we're just kind of kicking it and hanging out as much as we can."

But Cyrus isn't a single girl these days: she's dating Liam Hemsworth, her Australian costar in The Last Song.

"I think we're both deeper than normal people," she gushed in March of Hemsworth, 19. "What they think and how they feel."
