So embarrassed on what "I" posted on her profile pic?

[Headache]

I admitted to my best friend I had feelings for her in December and she told me she didn't feel the same. Its been awkward between us ever since but we've made a bit of small talk etc. I accidentally left my Facebook page open and my sister wrote on one of her profile pics 'hottieee' from my account to try and tease me. Its just the worst thing that could have happened. She 'liked' the comment but I think it would have generally made her feel awkward and now she's never going to want to see me again. She's not going to believe my sister wrote that either. What do I do?
