"Extra" talked with Ryan O'Neal at an event for The Farrah Fawcett Foundation in Los Angeles -- and he confirmed he'll be doing "Dancing with the Stars" next year... once he recovers from knee surgery.

"I'm going to get my knee done. I have one new knee, a titanium one, I'm going to get a second," explained O'Neal.

Actress Tatum O'Neal visited The Grove and talked with "Extra's" Mario Lopez about her new book, "Found: A Daughter's Journey Home" -- and about her father, Ryan O'Neal, and his recent interview on "Piers Morgan Tonight."

On the CNN talk show, Ryan told Piers there was "turmoil during my love affair with Farrah, and a lot of it caused by my kids, particularly Tatum."

Tatum told Mario she didn't see the interview, but later read the whole transcript. "I think it was taken out of context," she said. The actress has since seen her dad and said all was good. "I think he's sort of unhappy the way that it got misconstrued, if you will."

Actor Ryan O'Neal and daughter Tatum O'Neal share their story on OWN in a new reality show, "Ryan and Tatum: The O'Neals."

"We didn't have any script or anything like that. We just had each other," Ryan explained to "Extra's" Adrianna Costa, adding, "We have a history, quite a history."

Actor Ryan O'Neal is heading to Washington D.C. with daughter Tatum O'Neal for a special presentation in memory of Farrah Fawcett, who died of cancer in June 2009.

On Wednesday, February 2 (which would have been Farrah's 64th birthday), the family is donating several items to the Smithsonian's National Museum of American History -- including the infamous red bathing suit Farrah wore in her immensely popular '70s pinup poster.

"They'd like it, the Smithsonian, for their display," O'Neal told "Extra." Other items being donated are the original poster, a leather-bound book of Fawcett's personal copies of scripts for the first season of "Charlie's Angels" and more.

"Extra" talked with Ryan and Tatum at a special screening of "Paper Moon," their 1973 classic about a 1930s con man and the little girl he goes into business with. "The last time we saw it together was 12 years ago," the actor said. "It was a great script and they said I could use my daughter."

The longstanding rift between Ryan O'Neal and his daughter Tatum has been mended.

The two appeared at the premiere of "The Runaways" -- their first time at event together in decades.

"It feels great to be here with my Pops," Tatum told "Extra." Ryan added, "I'm proud, I'm proud!"

"Extra" has Ryan O'Neal in his first television interview since losing partner Farrah Fawcett in June.

O'Neal tells "Extra" special correspondent Ashley Hamilton that since Farrah's death he has repaired his rocky relationship with daughter Tatum O'Neal. Ryan said, "It's so nice to see her again. I've missed her terribly and that's a big step for me and her."
