MTV News spoke with Christina Perri, whose new track “A Thousand Years” will appear in The Twilight Saga: Breaking Dawn Part 1, to get her initial reaction to the news. Listen to a portion of interview below:

Christina goes on to tell MTV just how big of a Twilight fan she is:

“Yes, I am 1,000 percent a ‘Twilight’ fan. I can’t even deny that I am actually, in fact, a Twi-Hard and have a ‘Twilight’ tattoo,” she laughed, also revealing that she’s Team Edward. “I got a tattoo on my wrist that says ‘bitten,’ and it’s written in the font of all the book titles. So, yes, I am of one the big, geeky fans.”

On the flipside here’s MTV’s interview with The Joy Formidable, whose “Endtapes” made it on the soundtrack,  but who should be considered Twilight newbies:

‘I can’t say I’ve ever read one. I haven’t seen the films either, but I have heard the soundtracks, and I was familiar with some of the songs, you know, Metric and the Black Keys,’ frontwoman Ritzy Bryan told MTV News. ‘So I was more aware of the musical side of ‘Twilight’ than I was the books or the movies. Actually, I know very little [about the books]. I know they’re about vampires, and I know they’ve connected very much with an audience … so they’re obviously much enjoyed by a lot of people.’

The rest of the interview covers what their song is about and whether or not they’ll be at the movie’s premiere.
