"Game of Thrones" star Sophie Turner and DNCE frontman Joe Jonas were spotted kissing and cuddling each other at MTV European Music Awards in Oude Luxor Theater, Rotterdam, Netherlands. How did that happen?

According to Us Weekly, a fellow concertgoer Millie Janssen revealed that the 27-year-old singer couldn't keep his hands off Sophie throughout the show.

"Joe and Sophie arrived together before the show started," Janssen said.

"He had his arm around her as they walked in, and then he was holding her before the show. Joe and Sophie kissed a few times and were talking and drinking soda."

Janssen further added that when "Kings of Leon" started and the lights went out, the couple started dancing and singing together. They were dancing very close to each other and Joe kissed the 20-year-old actress few more times during then.

The source also stated that they left the show together after it ended. Joe and Sophie looked very much into each other and portrayed a very cute picture.

Pictures of them cozying up were posted on Instagram  and Twitter by fans.

However, this isn't the first time when these two were seen together. A recently posted Instagram picture showed that the couple also spent Halloween together. Joe was dressed as a Dalmatian while Sophie was sporting a pair of pink bunny ears.

Joe's last relationship was with model Gigi Hadid, 21. They split up and Gigi started dating former One Direction singer Zayn Malik. Joe also dated singer Demi Lovato and actress Ashley Greene.

Sophie Turner was seen with Wasps rugby star Danny Cipriani earlier this year in a Brixton nightclub.

According to an insider, The Sun reported that they were talking and holding hands and seems very cozy and intimate. They seemed happy with each other and were having really good time.
