Betty White is once again NBC's golden girl, as the octogenarian comedienne's weekend hosting spot helped 'Saturday Night Live' reach its biggest audience in 18 months.

According to the Hollywood Reporter, the episode averaged an 8.8 overnight rating, attracting an estimated 12-13 million viewers total. That's up 66 percent from last year, and marks 'SNL's' highest-rated show since Nov. 1, 2008, when John McCain made a special appearance during the peak of the Presidential election.

White led a team of returning 'SNL' funny ladies, including Ana Gasteyer, Tina Fey, Molly Shannon, Amy Poehler, Rachel Dratch and Maya Rudolph, during 'SNL's' Mother's Day show, with musical guest Jay-Z.

The former 'Golden Girls' star landed the hosting gig after a huge Internet push from fans on Facebook, a site she jokingly called "a huge waste of time" during her opening monologue. White, the oldest person to ever host 'SNL,' played up her "dirty old lady" shtick with a large helping of old age and genitalia jokes.

In her review of the show, TV Squadder Annie Wu called White's opening monolgue "sassy and cute and a little bit dirty."
