Nick Jonas is back on the market. The 19-year-old 'How to Succeed in Business Without Really Trying' star has officially split with girlfriend Delta Goodrem, 27. The couple were first linked together nine months ago.

"Nick and Delta have decided mutually to end their relationship," Australian singer's manager said in a statement. "At this point in time, they are both focused on their careers as they go on different paths. They remain friends and wish each other the best for the future."

The May-December romance began in 2011, shortly after Goodrem split from 'Australia's Got Talent' judge and former boy band member Brian McFadden, her boyfriend of seven years. Before dating the statuesque pop singer, Jonas was linked to 'Les Miserables' star Samantha Barks, Miley Cyrus and Selena Gomez.

Despite their eight-year age difference, the relationship seemed to work. The pair reportedly collaborated on songs and vacationed together in Mexico last fall.

Since they first began seeing each other, both stars have entered new projects, including Jonas' stint as J. Pierrepont Finch on Broadway and Goodrem's role as a coach on the Australian version of 'The Voice.' The Jonas Brother can next be seen as a guest star on the Feb. 27 episode of 'Smash.'
