"You know, she had an amazing five years on the show, and she learned so much from Joan [Rivers]," she told "Extra's" Mario Lopez.
"It was just her time. She's got to grow up, move into the big world," she added.
The E! Network announced Kelly Osbourne's departure from the show in February, a week after she expressed disapproval in the face of former co-panelist Giuliana Rancic's comments that Zendaya's dreadlocks smelled of weed and patchouli oil at the the Oscars.
