Diane Warren says we've taken enough crap from Donald Trump, so it's only fair to s**t on him.
We got the songwriting legend in WeHo Tuesday night at Craig's and asked her about the proposal to remove Trump's star from the Hollywood Walk of Fame. Warren's out-of-the-box response ... "I think someone should take a s**t on it!"
Diane -- one of the most successful songwriters in the world with 9 Oscar nominations -- goes even further with her potty talk.
It's not the first time Diane has trashed members of the Trump administration.
