The 15 rudest celebrities in Hollywood – See who’s number 1! (With Pictures)

9. Katie Couric

When you see Katie Couric on television, it is very difficult to even imagine her being anything other than sweet and charming. Apparently many people have on-screen personalities that are entirely different than their real-life personas. Katie allegedly made snide remarks and imitated Meredith Viera after she took over for Katie on Today, back in 2011. Even though Meredith isn’t on the “top of the nice tree,” there really is no reason to act like a schoolgirl when you don’t get your way. It has also been reported in the past that she is extremely rude when interviewing guests, and always seems to ask all the wrong questions.
