New couple alert — After a five-month romance with Gigi Hadid, DNCE frontman Joe Jonas is now being linked to actress Sophie Turner. The two were apparently seen getting quite cozy in Rotterdam, Netherlands.

The former JoBro and "Game of Thrones" star attended the pre-MTV Europe Music Awards Kings of Leon concert together at Oude Luxor Theater. Fans spotted them seated next to each other and photos were also published.

In one photo, Jonas has his arm wrapped around Turner as she holds onto his hand. One fan even said that she had seen the two kissing. 

"They were really close together," concertgoer Anne Charlotte told PEOPLE. "I didn't look very often because I was seated more in front of the room. The two or three times I was watching they were kissing. She was all smiley and he looked really sweet."

Based on what the fan saw, it certainly seems like romance is blossoming between the pair. She also continued on to say that Turner and Jonas seemed very comfortable with each other. 

It's possible that the two stars have known each other for quite a while. An insider also told the publication that Turner "has had a crush on Joe for a while, but Joe isn't going to be a one-woman guy right now."

The two also spent Halloween together with a few friends, as a photo posted on Instagram shows. Jonas can be seen wearing a dalmatian costume, while Turner is sporting bunny ears.

Jonas' band, DNCE, performed at the MTV Europe Music Awards. Turner, on the other hand, may soon have her hands full as "Game of Thrones" is currently filming in Spain.

Neither Turner nor Jonas has publicly addressed these dating rumors, though. And their representatives have not spoken out yet either. With that, it would be best to take this news with a grain of salt.
