This past weekend, new “Saturday Night Live” cast member Kate McKinnon made her debut, and by all accounts, was a hit. And that’s a good, especially since rumors persist that key lady cast member Kristin Wiig will be leaving at the end of this season. Here, McKinnon appears for a scant 30 seconds, doing a pitch-perfect impression of Bravo TV’s Tabitha Coffey. And after the jump, check out her impersonation of Penelope Cruz, appearing in a Pantene commercial with host Sofia Vergara. Enjoy!
