untrustworthy

A person who portrays themself to be something that they are not. Uses their cuteness to hide the evil they carry inside. Always out for themselves and will always get what they want at the expense of others.

My ex wife so evil, she was a total stephany.

There goes another untrustworthy politician, a real stephany.
