Tonight's Grey's Anatomy guest star, Demi Lovato, spoke with E! Online about what it was like to meet the cast, what a big fan she is of the show, and much more.
Demi plays an extremely troubled patient Alex must treat on "Shiny Happy People." Below are some excerpts from the 17-year-old Disney star's conversation ...
On making her boyfriend, Joe Jonas, tune in: "I don't think [Joe] has ever watched it but I'm gonna make him ... I'm gonna show him how amazing it is."
On what she said upon meeting some cast members: "Um, hi! Can I just say hi? I'm just ... a really big fan. I just saw Owen, and got really starstruck!"
"I'm a huge fan. Obsessed ... it not healthy. People know on my set (Sonny with a Chance), ‘OK, she's gotta be home at 8:45 so she can watch [Grey's] at 9.'"
On her role: "I'm playing a possible schizophrenic, and I hear every sound in my body from my heart beating to my eyes moving, to my muscles flexing, to my blood rushing. I hear everything going on in my body and I couldn't take it and I try to claw my eyes out."
On her makeup for the part: "It's a little Lady Gaga-esque ... I've been doing a lot of crying so it's probably worn off by now, but it's pretty awesome."
"There was a huge smile that came on my face then. My favorite is, don't tell, but I love Lexie! Lexie's like my character and I love her character so much."
Justin Chambers and Kevin McKidd also chimed in on their characters ...
Justin on Alex's relationship with Lexie: "It's a little physical. It's kind of a rebound. Alex married Izzie and said all those wonderful things and I don't think you just fall out of relationship that easy. But [Lexie is] a cute girl. Asweet girl. So maybe there's something there."
Kevin on Owen, Mark and fighting for Teddy: "They could throw down, the two of them. I'd like to see who comes out on top! [Laughs] Not in that way. But we haven't had a good fight scene since Derek and Sloan at the end of last season, so that would be fun."
