Chopra, who won the Miss World pageant in 2000, has become one of Bollywood’s most identifiable stars and, more recently, one of the few to achieve success in the West.
She has starred in the thriller series “Quantico” on US network ABC and, in her career as a singer, has released songs with US chart-toppers including Pitbull and The Chainsmokers.
Jonas first found success as a child as the frontman of The Jonas Brothers with his two siblings.
Also an actor on theater and in television, Jonas returned to music as a young adult with a new, mature image and has often been seen as a sex symbol. He has been romantically linked to a number of prominent women including Miley Cyrus and Selena Gomez.
People magazine said that, while Jonas and Chopra have known each other for some time, they began dating just two months ago and the relationship was serious enough that she introduced him to her mother in India.
