Pop star Joe Jonas has hinted he's split from actress girlfriend Camilla Belle after changing the lyrics to a break-up song during a weekend performance in Detroit, Michigan.

The teenager took to the stage with his Jonas Brothers band mates on Sunday and sang a rendition of Much Better - a track widely believed to be taking aim at his ex-girlfriend Taylor Swift.

However, Jonas suggested to fans his romance with Belle was now over after replacing the original lyrics, "Get a rep for breakin' hearts, now I'm done with superstars," to "Get a rep for breakin hearts, now I'm done with movie stars."

According to PerezHilton.com, Jonas also removed a necklace given to him by the 10,000 B.C. beauty during the set, with fans interpreting his actions as confirmation that he's now single.

The couple had been dating since meeting on the set of the group's music video for Love Bug last year.
