Rosie O'Donnell returned to "The View," and it was almost like old times.

Before launching into the show's famous hot topics, O'Donnell joked, "Is Hasselbeck here?"

She was, of course, referring to former co-host Elisabeth Hasselbeck, with whom O'Donnell repeatedly sparred during her one-year tenure on the show. Hasselbeck left "The View" last year for "Fox & Friends."

Rosie O'Donnell Will Return to 'The View'

O'Donnell, 51, hasn't been back since 2007 when she and Hasselbeck had a painful falling-out on camera.

Known for her strong opinions, O'Donnell kept them somewhat reigned in this time, reassuring "View" co-host and creator Barbara Walters, "Don't worry, I'll be good."

Indeed, Walters and O'Donnell remained civil, even while disagreeing on Dylan Farrow's renewed claim that she was sexually abused by her adopted father, director Woody Allen.

"I totally believe her," O'Donnell said without hesitation, noting too that she's a victim of sex abuse and is close friends with Dylan Farrow's mother, actress Mia Farrow, whom she called a great mother.

When Walters said Woody Allen was also a good father, O'Donnell seemed skeptical, but only said, "You can never really know what's going on in a house."

After Walters said, "We'll move on," O'Donnell quipped, "It's my first time being back. I'm afraid I'll be exiled again."

O'Donnell tackled other topics, including Justin Bieber.

"Fame is a tidal wave, it sweeps you away," she said. "Do I think he needs parental supervision? Yes. But he doesn't need to be deported."

And, when discussing Phillip Seymour Hoffman, she said, "It's time to stop shaming addicts."

O'Donnell also discussed her nearly fatal heart attack in August 2012 and her five children, including the youngest one with new wife Michelle Rounds.

In addition to playing a social worker on ABC Family's "The Fosters," O'Donnell has been doing standup to raise awareness of heart disease in women. A special of her standup comedy is being filmed for HBO, and co-host Jenny McCarthy invited O'Donnell to come back before it airs.

O'Donnell, who admitted to co-host Whoopi Goldberg that she sometimes misses the daily platform to express her opinions, promised to return. Giving Walters a kiss goodbye, she said, "You know I love you."
