When a nine-year-old begins a letter using quotes around "Tooth Fairy," you know he or she might be on to you.

The girl who wrote the letter, Lexi, left the letter under her pillow to tell her parents that she doesn't believe in the tooth fairy and that she knows the truth.

Lexi also drops a couple more truth bombs on her parents regarding her thoughts on the Easter bunny and Santa Claus.

Here's her letter:

Dear "Tooth Fairy,"
I don't believe in the tooth fairy any more. I know it;s you who gets the money and puts it under my pillow, mom and dad. I'm sorry if this is hard for you, but I'm 9 now. (P.S.) I don't believe in Santa Claus either.
Love, Lexi
P.S. - Daddy I knew it was you last Easter, hiding my Easter eggs!

She's a pretty smart kid, it doesn't look like much is going to get past her.
