Looks like Nick Jonas is lonely again. Jonas Brothers star has reportedly split from girlfriend Selena Gomez.

The teenage pair, both 16, has been romantically linked since last summer, but, despite repeated denials from both Jonas and Gomez, online gossips have continued to speculate about the status of their relationship.

Star magazine claims Gomez and Jonas, who once dated Miley Cyrus, had been dating in secret for almost a year – but have now parted ways.

And Jonas’ busy schedule has been cited as the reason for the break-up.

A source tells the publication, “He’s a hard boy to date. He’s very into his music, and any girl comes second.”

“Selena would often miss Nick, and he just wouldn’t be there. But they’re still friends. They’re both very mature. She won’t make a weird scene about it.”
