Nick Jonas' romance with Delta Goodrem is moving to the next level after the teen sensation took his new love along to his mum's birthday party.
The Jonas Brothers star, 18, has been linked to the Aussie singer - who is eight years his senior - since May (11), and they enjoyed a romantic break in Bali, Indonesia last month (Jun11).
Jonas made sure his new girlfriend was part of the celebrations for his mother Denise's birthday bash by taking her as his date to a family dinner at Los Angeles restaurant Villa Blanca earlier this week (begs11Jull11), according to Britain's Daily Mail.
Nick's brother Kevin was also at the meal along with his wife, Danielle.
Goodrem called off her engagement to Irish singer Brian MCFadden in April (11) after seven years together.
