Although Mary Hart has held the position of Entertainment Tonight host for 29 years, she's not going down without a fight.
The Insider host Lara Spencer, who is trying to get Hart's job, accidentally called herself the host of Entertainment Tonight while on the red carpet.
Oops! And Mary lost her shiz!
"She competely lost it and tossed her coffee at the screen," said an insider, who claimed Hart later apologized.
ET reps claims the outburst never happened.
