Let's hope it wasn't along the lines of I'm Too Sexy For My Shirt
We are used to Emma Watson and those very expressive eyebrows of hers acting it up on screen, but after forming a band with her Perks Of Being A Wallflower co-stars Logan Lerman and Ezra Miller, it sounds like she might be a popstar in the making.
Having grown up on the set of Harry Potter, Emma had the full high school experience while filming her new flick and even ended up making some sweet music with her FIT co-stars.
"Throughout the movie, we as a cast all made music together," Emma explained at the London press conference.
"So I sing, Ezra also sings and plays the drums, and Logan plays the piano and Mae Whitman is also musical..
"Most nights we would sit and play music, so that was really fun and when we were actually doing the tunnel scene we did have music playing.
If having a bit of a snog with Logan on screen wasn't enough for us to be jealous of, he apparently also ended up writing her a song while they were filming.
"Our band tentatively was called Octopus Jam.. I don't know how we came up with the title," she continued.
"Logan's actually like a classical composer. He actually composed a piece of music for his part in Perks and he composed a piece of music for me, and for Ezra, so he's very talented.
"He was more classical and then Ezra's more rock and roll, and I was somewhere in the middle just doing my own thing really!"
Oh what we would do for a listen to that song. Do you think it was something a bit romantic or maybe something a little closer to I'm Too Sexy For My Shirt?
We'd happily give either a listen, but what do you think about all this?
