Dating rumors reignited after pop singer Nick Jonas was spotted out on a romantic dinner date with actress Kate Hudson, Entertainment Tonight reported. The rumored couple was photographed together at Pace, a cozy Italian restaurant, on Wednesday after sharing a meal together.

The pair was seated at a corner patio table and spent four hours together, an eye-witness told ET. They were spotted leaving the restaurant shortly after midnight and shared a ride together in an SUV.

Hudson, 36, and the 23-year-old "Jealous" singer kept the PDA to a minimum, a source told E! News. "There was a light kiss exchanged" and "Kate touched Nick's leg at a point during dinner." They were also "lovely to the waiters" and were "generous" with their tip.

"There were laughs throughout the dinner and Kate had a huge smile on her face," the source added. "Nick was a gentleman. You could tell they like each other."

The pair sparked dating rumors last September when reports claimed that Jonas was hooking up with the "Almost Famous" star, according to Us Weekly. They were also spotted together at a Super Bowl 50 party last weekend.

"They seemed to be flirty at first, and then it transitioned to a very serious conversation," a partygoer told Us Weekly. "They started getting very cozy and whispering into each other's ears, even sneaking kisses and touches under the radar."

Hudson skirted around questions about her reported fling with Jonas during an interview on the Golden Globes red carpet last month, according to ET, but Jonas addressed his relationship with Hudson in a recent interview with Complex magazine.

"Kate's incredible," Jonas told Complex. "We had an unbelievable connection as two humans who just admire things about each other, and see something in each other that's beautiful."
