Saturday Night Live scene-stealer

Ana Gasteyer — best known for her impersonations of Martha Stewart and Celine Dion — has announced that she's leaving the show after six seasons. The 35-year-old funny lady, who gave birth to her first child in June, is leaving to pursue "new artistic challenges outside the realm of sketch comedy." Gasteyer's exit comes on the high heels of Molly Shannon's and Cheri Oteri's departures, and brings to an end a hard-won golden era for the patriarchal show's premier girls club. In other words, Tina Fey, you better bring it!
