Model Gigi Hadid and boyfriend Joe Jonas were together on Wednesday night as they attended his younger brother Nick Jonas' concert at Terminal 5 in New York City, reports Daily Mail.

Daily Mail posted several photos of the celebrity couple at the event. Hadid, 20, looked sexy in a pair of black leather pants, black cropped top that revealed her toned midriff, and a black leather jacket. She appeared to be wearing no make-up, showing off a radiant complexion.

Joe, 26, donned a black long sleeve shirt with zipped detailing and dark trousers.

The former Jonas Brothers singer reportedly took the stage during Nick's performance to spin tracks on the DJ turntables.

According to Daily Mail, Hadid wore the same outfit while she and sister, Bella Hadid, 18, toured the city earlier that day with their friend Cully Smoller.

Gigi and Joe are spending more and more time together. The couple is nearly inseparable.

On Tuesday, Gigi, Joe and "Keeping Up with the Kardashians" star Kendall Jenner, 19, watched the Women's Singles Quarterfinals tennis match between sisters Serena Williams and Venus Williams at the U.S. Open in Queens, reports E! News.

Gigi sat between Jenner and Joe, sharing in conversation with both and occasionally sneaking kisses from her man.

It was previously reported that the "Just in Love" singer may propose marriage to the fashion model during the Christmas holiday.

"He wants to make things more official with Gigi and has been telling friends that he would like to get engaged to her around Christmas," an insider said. "He is definitely in the planning stages to do something very romantic for the big moment. He is in no rush to get married, but he is in a rush to make her know that she is the one."

Joe and Gigi allegedly started dating after she ended her relationship with Australian pop singer Cody Simpson in May, but paparazzi captured photographs of the pair in September 2014, which led to rumors they were dating at that time. The couple initially denied dating rumors.
