Our girl Troian Bellisario (Spencer) doesn't seem like the type to get all weak in the knees from a celebrity, so it makes a lot of sense what she actually got starstruck from.

The Pretty Little Liars actress took to Instagram yesterday (May 29), showing off a photo of herself posing with a potted plant. She wrote, "Yes that's me. And yes that's one of the ferns from "between two ferns". You're lime green jell-o, gurl, Don't try to pretend. #starstruck."

For those of you who don't know, Between Two Ferns is an internet comedy series on Funny or Die, where host Zach Galifianakis does celebrity interviews between two potted ferns.

Leave it to Troian to get all blushy from a plant! Have we mentioned how much we love her?

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
