While Emilia Clarke plays the tough-as-nails mother of dragons on Game of Thrones, in real life the stunning actress isn't immune to the charms of her favorite sitcom star.

Appearing on The Graham Norton Show last week, the 29-year-old HBO star sat next to Friends alum Matt LeBlanc, and inadvertently revealed that she's got a massive crush on the 48-year-old actor.

Clarke, giggling and blushing uncontrollably, could hardly contain herself while sitting next to her crush, and all bets were off when he smiled and but his arm around her shoulder.

Clarke was even forgiving toward LeBlanc when he revealed that he stopped watching her show after Season 1.

"I watched it the first season, and then I kind of fell out of it, and then I tried to watch it this season and I don't know what's going on," LeBlanc explained.
"It's okay," Clarke assured him. "You've see the good bits."

Before the show was over, Clarke had a "slight request" for LeBlanc: "Would you be able to ask me how I'm doing?"

Not wanting to disappoint his special admirer, LeBlanc recreated his Friends character Joey Tribbiani's famous catchphrase, asking Clarke, "How you doin'?"

At which point the Me Before You star was suddenly beaming uncontrollably, and admitted that the infamous pick-up line still works.

Later in the episode, Clarke shared that she recently watched a particularly revealing episode of GoTwith her parents, which ended up being really embarrassing. However, Norton suggested the skin-bared sixth season episode might be a good chance to start watching the series again.

"Then I can really see how you're doin'" LeBlanc quipped, sending Clarke into a charming fit of laughter.

Recently, Clarke spoke with ET about the nudity in the HBO fantasy series, and opened up about how the show is "at the forefront of feminism" as it features "so many fabulous, strong women." Check out the video below to hear more.
