Friends teasing me about a girl that I do secretly admire...

adzz1
basically I'm 20years old at uni and I've got really immature friends, well they could probably say the same about me lol. but anyways, one day I was talking to a mate about whose the fittest girl in our year, at the time I didn't like her but she is very pretty, she's got the looks of a model. I said she's the nicest in our year but at the time I meant that she is good looking and not that I like her...now ever since that day, he has told my other mates that I like her and they always tease me in lectures when she walks in or if she walks past. now I'm pretty sure she has heard them joking around and stuff when ever I'm there. but as time has gone on, I've realised I do actually like her but I'm really shy when it comes to girls. she's the shy type too but I'm sure she knows that I like her as she's heard my mates messing around. but the thing is, one time we were all waiting at the lifts and she walks through the doors but she sees us all there, instead of waiting for the lifts she decides to get the stairs! is this cause she feels intimidated by us or that she doesn't like me? this really freaked me out, I think she thinks I'm a wierdo and she doesn't want anything 2 do with me cause she just walked away wen she saw us.

now just to shut my friends up, I'm thinking of talking 2 her infront of them but making sure they don't hear anything and I want her number, but I'm scared she doesn't like me and will embarass me infront of every one. what shall I say to her? how can I ask her out, I was thinking something like:

"hi sammy you probably heard my m8s messing around that I like you this is not true, what I said was is that I think ur really pretty which is a compliment. just ignore them they act like kids, but I was thinking if ur free sometime this week we could go grab a coffee or something?"

does this sound cheesy? please help, is there anything extra I could do or say? I'm scared if she says no she's definitely gonna know that I like her and every time I see her its gonna be really awkward...and by me speaking to her it will shut my m8s up right?
