Nick Jonas and Priyanka Chopra are reportedly engaged after months of dating, a source told People. The singer proposed to the Quantico star for her 36th birthday while they were in London together, according to the sources.

Jonas was apparently serious about choosing the engagement ring. He reportedly closed down a Tiffany & Co. store in New York City just so he could choose the right piece.

The couple has not yet responded to or confirmed the news.

However, the sources said the pair is “so happy.” Another source closer to Jonas said he’s “very, very happy.” “His friends and family have never seen him like this, and they’re all really excited for him. He’s definitely very serious about her,” the source added.
