Friend drama :( PLZ ANSWER?

My bff and i were @ the pool and we started mimicking celebs. SOOO, she's a pro taylor swift, I'm a pro camilla belle. (plz don't hate either one of us and answer nicely despite our opinions) I got on the diving board and said, "Now sit it the corner at just THINK abt what u did" in a little immature kid voice, did a sas walk and jumped. She said, "i'd do camilla but how do u mimick stealing a boyfriend on a diving board? You can't." blahblah boyfriend stealer for like 20min. She kept defending everything that obviously made since with a baby's answer. I'm ticked. Don't think THIS is my bff. She won't speak to me now bc she <3's someone she doesn't even know. HELP....????!!!!
