Sophie Turner on dating Joe Jonas: 'I am very happy'

July 6 (UPI) -- Sophie Turner says she's "very happy" with boyfriend Joe Jonas.

The 21-year-old British actress opened up about her relationship with the 27-year-old American singer in the August issue of Marie Claire U.K.

"I'm very happy," Turner told the magazine before discussing the downsides of dating a fellow celebrity.

"You do feel like you're living in a fishbowl," she said of public interest in her personal life. "It's frustrating [that] it's the most mundane things that make the news -- how boring!"

Turner and Jonas were first linked in October, and were spotted kissing at a Kings of Leon concert the next month. The actress discussed the upsides of dating a celebrity in the May issue of InStyle.

"[I] keep things pretty private," she told the publication.

"I found it easier to date someone who understands the industry or is in that world," the star added. "You realize that you're not going to see each other all the time. And you don't feel like a jerk when you're like, 'My publicist says I can't do this ... '"

Turner is known for playing Sansa Stark on the HBO series Game of Thrones, which will return for a seventh season July 16. Jonas came to fame with the boy band Jonas Brothers, and presently sings with DNCE.
