'Castle' Guest Star Carly Rae Jepsen Is 'Stoked' to Be on the Show

The singer will guest star in tonight's episode.

The singer will guest star as herself on an episode of "Castle."

She’ll be singing her new song, “I Really Like You,” and also will have a couple of lines of dialogue during the episode.

“Did some serious acting on @Castle_ABC,” she tweeted late last week. “Ok, I had two lines, but still pretty stoked!”

In a preview clip from the episode, Castle, played by Nathan Fillion, tells the singer he’s a huge fan. “Thanks, that means a lot to me,” she responds.

Before he can gush anymore, Jepsen, 29, is called on stage to perform.
