Nick Jonas has a celebrity crush, and just can't keep his cool.

The "Chains" singer -- and Game of Thrones superfan! -- couldn't help himself from stopping by BBC Radio 1's Breakfast Show on Thursday when he found out Emilia Clarke, who plays Daenerys Targaryen on the HBO series, was going to be there.

During Clarke's interview, host Nick Grimshaw surprised her by inviting Jonas to the studio. When the 23-year-old pop star walked in, he nervously put on his headphones and joked, "You really set me up for failure to not look cool at all."

"I've actually already met Emilia," he revealed, as his cheeks started to get a little rosy. "At the Oscars after-party. It wasn't like, 'I'm a fan of your show.' Actually, that was part of it, but I was like, 'I'm also a fan of your Instagram.' Which I don't know if it's a weird thing to say."

A beaming Clarke was clearly flattered by his compliment, insisting that it was "an amazing thing to say!"

"The minute I walked away I was like, 'That sounded stupid,'" he recalled. "That was maybe after one or two cocktails that I said that. It was highly embarrassing."

But when asked why he likes the 29-year-old actress' Instagram so much, he had no trouble listing off the reasons.

"She posts great stuff," he explained. "Like insight into the show, behind-the-scenes pictures and stuff."

Watch the full clip below.

Following the interview, Jonas took to his favorite app -- Instagram, of course! -- to share a collage of the hilarious trio.

"Two Nicks and a queen of dragons," he captioned it.

Jonas isn't the only one who's gotten flustered over a sexy star, however. Last month, Clarke was a guest on The Graham Norton Show with Matt LeBlanc. While sitting right next to him, she adorably confessed she had a massive crush on the former Friends actor.
