Kate McKinnon will appear on this week's live episode of Saturday Night Live.

According to Nikki Finke's Deadline Hollywood, McKinnon will make her debut on Saturday's show, which is being hosted by Sofia Vergara, a co-star of ABC's Wednesday night comedy Modern Family.

If picked up as a regular, the 28-year-old McKinnon would become the show's first openly lesbian comic in its 37 year history, and the show's first openly gay cast member since Terry Sweeney in 1985.

McKinnon, who won cabler Logo's NewNowNext Award for Best Rising Comic in 2009, joined the cast of Logo Network's Big Gay Sketch Show in 2006. She remained a regular on the program for its entire three-season run.

In 2007, she discussed with AfterEllen.com “always wanting to be a lesbian comedian.”

“As minorities, we're on the fringe, and there's just something so wonderful about that perspective, something so inspiring,” she told the site dedicated to lesbian entertainment. “If you're part of that minority, you can make fun of those people while respecting them and lifting them up.”
