'Always Sunny in Philidelphia's Kaitlin Olson to be 'The Mick' on Fox

Bird woman and butt of the joke Dee Renyolds will be toplining a new show on Fox. Real life actress Kaitlin Olson, Variety reports, is said to star in the comedy The Mick, a show that revolves around a foul-mouthed woman as she raises her sister's spoiled children. What's interesting about the deal though is that Olson is said to be starring in both series -- Sunny, which was renewed by FX for a 12th season and The Mick. Writers John Chernin and Dave Chernin (both from Sunny) will pen the series.
