You'd think Mark Hamill was living in a galaxy far, far away. Or that he stopped following the music scene a long time ago.

The Star Wars actor just had a hilarious Twitter moment where he was blissfully unaware that he was quoting one of the most talked-about songs of the moment.

"Thank you, next," Hamill wrote, which incidentally is both the title and the chorus of the latest song by Ariana Grande.

Although Hamill wrote "you" and not "u", like the lyric is technically spelled, Grande was quick to pick up on what she thought was a salute to her song from Luke Skywalker himself.

But Hamill then admitted that he was, in fact, not aware that he was quoting a hit song.

"You know you're out of it when someone suggests you tweet what you think is just a random phrase that turns out to be the title of the new album by Ariana Grande, one of the most popular artists in the history of showbiz," Hamill wrote.

Grande was not in the least offended by that, though. In fact she seemed pretty entertained by the whole misunderstanding.
