Nick Jonas, 28, and Priyanka Chopra, 39, have stepped out in London, after recently celebrating the three-year anniversary of Nick getting down on one knee. The couple were spotted leaving Crown London Aspinalls Casino around 4am on August 5, after enjoying a romantic date night at Amazonico restaurant in Mayfair. The Jonas Brothers hitmaker held onto the actress’ hand as they left the private gaming club, looking very chic.
