When 'House of Cards' actress Kate Mara stopped by 'Jimmy Kimmel Live' this week, the host couldn't resist poking a little fun at her love for One Direction -- specifically, at this tweet of perfection.

When Kimmel asked her if that really happened, Mara was quick with the response:

"It happens most nights," she joked. "Have you seen Harry Styles' face?"

When the comedian further prodded her to talk about the 1D cutie, Mara was diplomatic.

"I like all of them, I'm not just going to say Harry Styles," she replied. But when asked to name the rest of the guys in the group, she needed a little help from Kimmel and the studio audience, accidentally calling Niall Horan "Niles" and forgetting about Louis Tomlinson completely. Whoops!

But you can't really blame her -- she's still a fairly new Directioner.

"Strangely enough, the only reason I'm even aware of One Direction is because [boyfriend] Max Minghella and ['Teen Wolf' star] Dylan O' Brien, who's sort of a teen heartthrob himself, introduced me to their music."

And when Kimmel jokingly asked her if she was babysitting them while listening to 1D, Mara quipped: "I'd babysit One Direction any day."

So, what would happen if she ever met Mr. Harry Styles himself?

"I feel like with Harry, I'd play it cool," the 31-year-old actress said before trailing off into laughter and changing her mind. "I'd turn into a 14-year-old."

It looks like she is closer to getting that chance, based on this screenshot she posted to Twitter last night. Aw, yeah.
