What did Ellen DeGeneres lie about?

A common rumor was that Ellen DeGeneres lied about using CoverGirl cosmetics, when in reality she used show make-up while on the set of her TV show. In reality, though, that rumor is false and she still has a good relationship with CoverGirl

According to the CoverGirl website, the make-up brand still supports Ellen DeGeneres, highlighting her accomplished television and movie career, as well as admiring her for her humanitarian work. They did not "drop" Ellen DeGeneres as a spokesperson for the make-up brand, a public misconception that led to a rumor that DeGeneres must have lied about using their product.
