Rosie O'Donnell filed for divorce six months ago, and apparently that's long enough for her to stay single, as she's reportedly started seeing Tatum O'Neal. “They are romantically involved,” a source ever-so-bluntly tells People magazine. “It’s a bicoastal relationship.”

“They are confidantes. They are hanging out. They have seen each other on both coasts, in Nyack and in Los Angeles,” the source adds. And in Manhattan, as it turns out, as the two have been spotted over the past month taking in a Broadway show and dining at Da Silvanno.

So what exactly brought this on? Well, a rep for O'Donnell says the two have "been friends for years." Maybe it was the whole super-Irish last name thing that brought them together. Think about how adorable a hyphenated version would be? O'Donnell-O'Neal! O'Neal-O'Donnell! Oh boy!
