So what? Practically every celeb who professes to support the deeply hypocritical PETA wears leather. Some of them even wear fur. Helen is very low on the list of offenders.
That she doesn't understand that non cruelty-free skins are used to create leather goods is an entirely different matter. But then she's far from alone there either.
Far from being a dimwit I think someone is advising her to act in this ditsy way to get the column inches and...guess what..it's working!
Making a big thing of wearing a PETA T shirt and then tweeting a picture of er lunch
with a cleverly positioned leather bag centre stage
..that is engineered, mark my words
