Courtney Galiano may not be a name you recognize, but "Glee" fans may recognize her face. Or, rather, her moves.

The former "So You Think You Can Dance" finalist and All-Star appears in "Glee: The 3D Concert Movie" as one of the backup dancers. This gig comes after appearing on the hit Fox television show a couple times – once as a member of Vocal Adrenaline, natch – and following familiar faces like Lea Michele and Cory Monteith on tour as a dancer both this summer and last.

The first time she appeared on "Glee"… The first episode that I did was “This is a Man’s World” when Quinn actually sang “This is a Man’s World” and I was pregnant, so it was pretty interesting. I sent my parents a picture; I was like “Surprise!” It was kind of funny.

Her gig in the movie came to be… Last year, they had a big audition for the "Glee" tour so this year they actually used people that have been on the show. A bunch of the dancers were Cheerios or part of Vocal Adrenaline, so I think they went off of that and chose people that they’ve previously worked with.

Learning all those numbers… The rehearsal process was insane. They were still shooting the show when we started rehearsing so the cast never really got a break. The dancers had to help them out in that sense.

When she found out the tour was going to be a movie… I actually didn’t know they were going to make it into a movie until I got the job. We were all pretty ecstatic.

Seeing herself in 3-D… When we were filming it, I wasn’t sure really what to expect. But then, in between the takes and stuff, we got a chance to see it, and it was insane. I was like “Oh my gosh, my friend and I are in 3-D! That’s the craziest thing on earth." … It’s definitely surreal.

When she sees her name in the credits on the big screen… It’s going to be the weirdest thing ever. I mean, I’m definitely so excited about it but I don’t think I’m going to think it’s really real until I’m there, and I’m actually watching it. I still haven’t gotten the chance to grasp it. When I did “So You Think You Can Dance” – it's still weird when I’ll watch it or even when I did “Camp Rock,” that was a TV movie. So the fact that I’m going into the theaters to watch my friends and I, it’s so surreal. I’m like, “Yeah, Mom, you can go see me in the movie theaters.” Like, what?!

When she actually said this to her mom… My mom was having a heart attack. She is going to be having a heart attack. It’s definitely going to be pretty awesome for all of us.

When she's not appearing in movies and on television… I started my own dance convention called “The Beat.” I’m really excited about it. I’m having a lot of the people from “So You Think You Can Dance,” and Brooke Lipton, who was the assistant choreographer on "Glee," – they're all part of my faculty. We’re going to three different cities this year, New York, Dallas and Orlando. And I’m just really nervous. It’s a big business venture for me. It’s a really great opportunity for me to share and bring the people that have inspired me, the people I’ve learned so much from, and pay it forward and have young kids that want to do it and want to dance and learn from the people that they see on TV.

And the winner of "So You Think You Can Dance" this season will be… I’ve worked with Marco before and he’s a doll. They’re all such sweet kids and I’m rooting for all of them. Because I know what it’s like to be backstage – it's funny because nobody really even focuses on winning. I feel like everybody just focuses on the task at hand for that week. But I’m rooting for all of them for sure.
