Is Beyonce a beautiful liar!?!

NOOOOOO not Beyonce!!! Rumor is that B is a liar when it comes to writing her own music...

Okay so we all know that a lot of artist are given credit for writing and they only come up with a few lines or so... but sources are saying that Beyonce only changes a word or two and gets all the credit...

I don't believe it I don't believe it(covering my ears)

Sooo I ask you again could it be that Beyonce is just a beautiful liar!?!
