That's fucked up.

Looks like your buddies made it seem like you were talking to them about getting into her pants right after you met her. I that's the case then, hell...you had it coming.

Probably not though, so tell her that your friends were being dickwads. No need to apologize for anything because you didn't do anything wrong. If she's got a problem with your friends making idiot comments...then it's not worth it.
