Oprah's best friend Gayle King says not to feel too bad for the talk show host, who will step down from her daytime series in 2011.
"After 25 years, it's just time to go while you're on top, and maybe have a semblance of a life," King told "Good Morning America's" Robin Roberts Monday morning.
"Listen, no pity party for Oprah, because she has a great life and does wonderful things," King went on. "But at the end of the day, it really is her life and it's time. This weekend, for instance, she went to California with a big bag of books and was so happy to know that was what she's going to do."
But Oprah isn't sure of her next move, King says.
"She's riding off from 'The Oprah Winfrey Show' as we know it, but she's not riding off into the sunset," said King. Oprah is starting her own network, OWN. "I know there's going to be a next chapter."
King doesn't think Oprah's shoes "can be filled, but I know I'm biased."
She also dashed rumors that she'd be replacing her best friend on the air.
"I have never heard that conversation from Oprah. Do I want to do something with the OWN Network? Absolutely, positively. [But] Oprah hasn't asked me to replace her, and she's got my number!"
King says she's already in "Oprah withdrawal" even though her pal has one more season on the air.
"We're planning stuff that will blow you away... a very nice farewell," she said.
But the end of the show is bittersweet.
"I'm happy for her, and really sad for me," King said. "I'm happy because I know for her it is the right decision. She is so at peace with it. She's very much alive and happy."
