An eyewitness tells People that she saw the two kissing during the show. "The two or three times I was watching they were kissing," the source tells the magazine. "She was all smiley and he looked really sweet. They seemed pretty comfortable."

And this isn't the first time 27-year-old Jonas and 20-year-old Turner have been spotted hanging out. The two spent Halloween together, with Jonas dressed as a dalmation and Turner dressed as a bunny.

But this isn't the only recent chatter surrounding his love life.

Last month, a source told ET that Jonas was "getting serious" with Brazilian model Daiane Sodre after the two dated throughout the summer. "She gets along with his friends and the band -- everyone seems to like her!" the source noted.

Still, in September, Jonas told Women's Health magazine he was single -- and also made it clear he was against public displays of affection.

"No, not at all," he said when asked if he was a fan of PDA. "Look, when you really like somebody, that kind of goes out the window. But even around friends and stuff, I think you keep that for the bedroom or behind closed doors."

...Perhaps Turner is changing his mind on the topic?

ET spoke to the British actress in August at Variety's Young Hollywood event, when she admitted that she doesn't have much time for a personal life due to her busy GoT schedule.

"I guess, you know, you stay in touch with your friends...I try and make as much 'me time' as possible," she said about how she tries to find a balance. "I try and get as much in of that as possible because otherwise you can get very overwhelmed. I meditate quite a lot just to balance my life out but yeah, it's tricky. ... I'm finding my way."

She also gushed about another handsome man -- her co-star, Kit Harington.

"It's such a blast working with him, and we do kinda have that sibling relationship," she revealed, laughing, "We tease each other, and he really gets under my skin ... He’s the best, I love him."
