Betty White is finally making her debut as a Saturday Night Live host.

The 88-year-old former Golden Girl -- who appeared in last summer's The Proposal and got tackled during a Snickers Super Bowl commercial -- will host SNL's May 8 episode, NBC confirms.

SNL's executive producer Lorne Michaels, who says he has "always wanted" White to host the show, was moved by the nearly half a million fans who petitioned to get her a spot via Facebook's "Betty White to Host SNL (please?)!" group.

"It took on a groundswell," Michaels tells USA Today of the fan movement. "It isn't something we would have said no to," but the campaign "validated that, 'Oh, that'd be fun.' ... It was the outpouring of affection from fans, and we feel the same way."

Taking the reins for SNL's Mother's Day episode, White has long been pursued as a host.

"Years ago, I turned it down three times," White says. "It's so New York, and I'm not New York at all. But my agent said he'd divorce me if I didn't do it, and I love my agent."
