People faking pregnancy

So my cousin found out I was pregnant. Well. Now I noticed she is saying she is and posted a picture on her Facebook announcing it to everyone. I knew she was lying. So went online and found the exact picture of the positive ept tests that she posted a picture of.

It really drives me up the wall. And her "husband" is going a long with it. Unless she lied to him too. She does this attention seeking stuff anytime something good happens to me or my sister. Its just annoying.
