Chopra, 35, did not share any photos with Jonas, but she did post a photo from New York on July 5.

"Summer sun makes me happy...you make me happy... thank you for the 25 million love...grateful and blessed," she wrote, referring to her 25.1 million followers.

Jonas and Chopra have been nearly inseparable since they went public with their romance in June. Since then, Chopra joined Jonas for his cousin Rachel Tamburelli's wedding in New Jersey. The two also went to India to meet Chopra's mother. They also went to Brazil, where Jonas performed at the VillaMix Festival on June 30.

Chopra shared a video from Jonas' performance on her Instagram Story, with only "Him" and a heart eyes emoji written on it. This was a reference to a June 22 video Jonas posted of Chopra from Mumbai, where he only wrote "Her" and included a heart eyes emoji, too.

"He's crazy about her and is excited about where things are going," a source told E! News last month. Chopra "is different from anyone else he's dated. She's very mature and sophisticated. It's been a breath of fresh air and he's very happy with her."

Another source told PEOPLE their relationship is "getting serious" and the two are "very happy."

"It's a huge deal that Nick brought Priyanka to his cousin's wedding," a Jonas friend told PEOPLE. "He's dated a lot over the last couple years but it's never been anything serious, so this is a big step."

Back in May, Jonas released his latest single, "Anywhere," with producer Mustard. As for Chopra, she just starred on ABC's now-cancelled Quantico and is set to make the movie, Bharat in India.
