It is reported that singer Nick Jonas and Quantico star Priyanka Chopra are engaged after dating for two months.

A source told US celebrity magazine People that 25-year-old Jonas proposed last week on Chopra's 36th birthday - July 18 - in London.

"They are so happy," said the source.

A "Jonas source" told People that the musician is "very, very happy".

"His friends and family have never seen him like this, and they're all really excited for him," said that source.

"He's definitely very serious about her."

Reports of the engagement began after the director of the film Bharat, Ali Abbas Zafar, tweeted that Chopra was leaving the project because of a "very very special" reason, telling the filmmakers "in the Nick of time".

"Team Bharat wishes @priyankachopra loads of love & happiness for life," the director added.
