A Jonas source tells PEOPLE the singer is “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 says.

Late Thursday night, Chopra’s director for the Indian filmBharat, Ali Abbas Zafar, announced the actress would be leaving his project in a cryptic tweet alluding to her boyfriend, which launched rumors among the Indian press the two stars were engaged.

An insider previously told PEOPLE Jonas and Chopra stayed in touch after hitting it off last year but things really heated up between the pair when they introduced each other to their families.

“It’s a huge deal that Nick brought Priyanka to his cousin’s wedding,” a Jonas pal previously told PEOPLE of the duo, who posed together at the 2017 Met Gala. “He’sdated a lot over the last couple yearsbut it’s never been anything serious, so this is a big step. Nick and Priyanka really like each other, and his family enjoyed getting to know her as well. She fit right in!”

Then, on June 22, Nick and Priyankatraveled to Indiawhere they met her mother Madhu.

“We’re getting to know each other and I think it was a great experience for him,” Choprapreviously told PEOPLE.

“That’s what he said. I think he really enjoyed it,” she added of theirweek-long getawayin the country — during which time sheintroduced Jonas to her mother Madhuandattended a friend’s wedding. “It was really beautiful. He had a great time.”

But [in] 10 years, I definitely want to have kids. That is, it’s going to happen in the next 10 years. Well, hopefully earlier than that. I’m very fond of children and I want to be able to do that.”
