Auds went gaga for Lady Gaga last night, as her hosting gig helped "Saturday Night Live" match its best overnight rating since March.

In Nielsen's metered markets, "SNL" did a 4.9 household rating/12 share, making it the night's No. 1 program.

The show hasn't done a higher overnight score since the March 9 episode featuring Justin Timberlake as host and musical guest. That installment of "SNL" ended up averaging 8.4 million total viewers in the nationals, so this episode figures to be in that ballpark.

In adults 18-49, this week's "SNL" did a 2.6 rating/9 share, matching the show's best since Miley Cyrus hosted on Oct. 5.

Lady Gaga was the host and musical guest on Saturday and was featured in a number of sketches, including as a very enthusiast dance mom and an Apple Store Genius. The show's final bit saw Gaga playing herself at age 77 in "Upper West Side 2063."
