Nick Jonas and Delta Goodrem have called it quits after 10 months together.

Goodrem's rep released the following statement, "Nick and Delta have decided mutually to end their relationship."

The couple were very hush-hush about their relationship at the beginning ... claiming to be collaborating musically. However, last year, they finally stepped out as a couple.

The 27-year-old Aussie's rep added:

    “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.”

Jonas is currently performing on Broadway in the play How to Succeed in Business.
