It's been just over two months since legendary comedian Joan Rivers passed away, but it hasn't been nearly long enough for her friend and "Fashion Police" co-panelist Kelly Osbourne to fully grieve the loss.

Osbourne stopped by TODAY Monday and talked about the tough time since then.

"I can't lie and say that I'm [doing] amazing," the 30-year-old reality TV star and fashion designer admitted. "It's something, to be honest with you, I really don't like talking about because I haven't been able to mourn and grieve the way that I want to."

One of the reasons Osbourne feels so reluctant to discuss Rivers is because she keeps hearing one question she just can't stand.

"Not one person that I have seen, or [who has] walked up to me or spoken to me since the day she passed has … [well,] the first thing that comes out of their mouth is 'Who's replacing Joan?'" Osbourne recalled. "And I have actually started to enter my angry phase, so it's not been fun."

The fact is there's just no replacing Rivers on "Fashion Police," no matter what casting decisions may be made in the upcoming season. She was one of the founding members of the fashion-snark panel and certainly the most outspoken.

But Osbourne will be back for whatever the future holds on the show when it returns in January, and she's keeping Rivers in mind all the way.

"I kind of live my life right now by: What would Joan do?" she explained.

And Osbourne knows exactly what Rivers would do if she didn't live life to the fullest now.

"She'd come back from the grave, slap me in the face and tell me to go back if I didn't do it," she smiled.
