Nick Jonas dating Delta Goodrem?

Nick Jonas is allegedly romancing Delta Goodrem.

Jonas and Goodrem are said to be dating after the singer ended her relationship with fiancé Brian McFadden last month.

The 18-year-old, who has previously been linked to Miley Cyrus and Selena Gomez, was seen leaving the ArcLight cinema in Los Angeles last night holding hands with the Australian popstar.

The 26-year-old and McFadden split in April after a six-and-a-half year relationship because they had "grown apart".

A statement released by their publicist at the time said: "Delta Goodrem and Brian McFadden regretfully announce that they are no longer engaged, and after much consideration, have mutually decided to end their relationship.

"This decision has been made with a lot of soul searching from both parties with the realisation that they have grown apart. They leave the partnership with respect for one and other, wishing each other success and happiness for the future."

However, the pair are still close and McFadden recently praised his ex-girlfriend on Twitter.

He wrote: "Finally got to see dwts. @delta_goodrem was amazing. She looked, sang and performed like the superstar she is. So proud of you D x (sic)"
