The photos of the newly minted couple were published by the Daily Mail as they walked arm-in-arm while arriving at Laguna Grill and Rum Bar for the beachside wedding ceremony.
The 25-year-old songster's brother Kevin Jones served as a groomsman and his wife, Danielle Jonas, was a bridesmaid on the big day.
Nick appeared to wear a navy blue suit and white shoes as he carried a gift for the bride and groom. The 35-year-old Bollywood-Hollywood actress, meanwhile, was looking stunning in a gold wrap dress, matching heels and sunglasses.
During the ceremony, at a point, the two stood up and recorded video of the wedding on their smartphones.
The next morning, the singer and the Quantico star had brunch together with his family and other wedding guests.
In the photos obtained by Daily Mail, Nick can be seen wearing a red plaid shirt, a baseball cap and sunglasses, while Priyanka sported a white floral dress.
As previously reported, multiple sources confirmed on May 29 that Prinka and Nick, who attended the Beauty and the Beast Live concert at the Hollywood Bowl on May 2, had started dating.
Following the Friday night outing, the pair attended a Los Angeles Dodgers game on May 26 and they looked very close and were all smiling.
Last year, following Nick and Priyanka's arrival of the pair at Met Gala, the Baywatch star had an interview with Jimmy Kimmel, where she went blush when she was asked about her relationship possibility with Nick.
Meanwhile, Priyanka previously dated Indian actors Shahid Kapoor (2009 - 2011) and Harman Baweja (2007 - 2008).
