Lionel and Nicole Richie Lionel and Nicole Richie

In their first joint interview in six years, Lionel and Nicole Richie appeared on Larry King Live together Thursday. Why now? Unclear!

What's that? Lionel has an album to promote? Ah, I see. Just Go (in stores now) features collaborations with Ne-Yo, Akon, Tricky and other youngfolk. "I just wanted to just come and support him and just — you know, just show how proud I am of him," Nicole said. Aw.

The pair talked about their turbulent relationship through Lionel's success, Nicole's drug use and subsequent rehab and how Nicole's boyfriend Joel Madden and 15-month-old daughter Harlow have brought them closer.

(Guys, Lionel Richie is almost 60! And a grandfather! He no longer dances on too many ceilings, ifyouknowhuti'msayin. I just felt a gray hair surface.)

In a teary moment, Lionel recalled the moment when he and his ex-wife Brenda, Nicole's mother, realized the severity of Nicole's addictions. "I came in and I said, 'I have some good news and I have some bad news. The bad news is that Nicole is going to die. The good news is, she doesn't have to.' I remember that look on her face of sheer panic," he said. 

But Nicole doesn't blame her father for her troubles. "Look, I really believe that you need to take responsibility for your own actions. I could sit here and give you a million excuses. My parents were divorced or this or that, but I made the decisions to do the things that I've done and I made mistakes," she asserted. "Everyone's made mistakes."

Nicole, who is pregnant with her second child with Madden, said they will probably get married, but not any time soon. "I think for both of us, we are going to do it because we want to, not because that's what you do. We're going to do it when the time's right," she said.
