I'm now the office whore

So I invited my colleague to my swimming pool to take pictures of me. She sent them to another colleague without my knowledge then he sent them to my supervisor. Now, my supervisor thinks I was the one who was in on it and she's now going to tell the big boss. Who obviously is now going to think I'm some kind of office hoe. I've been crying non stop this morning and now have to go to a meeting with everyone and now I don't know who knows. I honestly want to leave right now because I'm so embarrassed!!! What should I do?
