Help!!!!!!!!!!!!? please?

Im a cheerleader so i was in the locker room undressing. i was the last one so i decided to take me time. i strip down to my underwear and bra and i took off my bre and panties right after to apply fresh ones. my friend saw and told me i shouldnt be undressing so slowly but she kept on staring as i was naked. i felt uncomforable so she left.as i was putting my bra on 20 or 30 guys come in and when they see me,they laughed.......turns out the head cheerleaders told them there was a stripp show.i tried 2 talk to her but she says she saw me undress and told the guys. now what should i do?
