Mary Hart Leaving ‘Entertainment Tonight’

“It’s time for a change,” Hart said of leaving the show after nearly three decades

After nearly three decades as host of "Entertainment Tonight," Mary Hart is calling it quits.

Hart announced Thursday that she plans to leave the show after the upcoming season, which launches Sept. 13. Her exact departure date has not yet been revealed.

Hart joined the syndicated showbiz newsmagazine in 1982.

“I've reached a point when I clearly realize it's time for a change," Hart said in a statement.  "There are many things I want to do in my life and I'd better get on with them. It will certainly be with mixed sentiments that I say 'goodbye' at the end of the season, but it will definitely be with a sense of celebration…30 years of Entertainment Tonight, are you kidding me?  That's an accomplishment and something I'm very proud of!”

“Mary is one of my closest friends and although I respect her decision I will miss her tremendously. Right now we are focused on making this next season the very best in her long history with ET," series executive producer Linda Bell Blue said.

No decision has been made on who will replace Hart.
