The Mother's Day actress, 36, wore a sexy sheer top for the night out, which exposed her black lace bra. She finished the look with a jean jacket and a crossbody bag. The "Chains" singer, 23, rocked a black jacket and a hint of scruff.
Us Weekly broke the news last September that Hudson and Jonas were hooking up. (Jonas briefly cooled things off with Hudson soon after.) The on-and-off pair reunited during a Super Bowl 50 party on Saturday, February 6.
"They seemed to be flirty at first, and then it transitioned to a very serious conversation," an onlooker told Us. "They started getting very cozy and whispering into each other's ears, even sneaking kisses and touches under the radar." They were also joined by Derek Hough, who Hudson had a brief fling with in 2014.
While it's not clear what's going on with them now, Jonas obviously holds her in high regard. "Kate’s incredible. We had an unbelievable connection as two humans who just admire things about each other, and see something in each other that’s beautiful," he told Complex magazine last month, when asked about their sex life. "Out of my best effort to respect her and her privacy, I’m not going to say if we had sex or not. But we did have a beautiful connection. Even now I have so much admiration and respect. She’s amazing."
Hudson's not the only woman in his life, though. Jonas is also seeing where things go with actress Lily Collins.
"Nick really likes Lily," a source previously told Us. An insider added: "Nick’s single and having fun. Right now it’s not exclusive."
