Excluding a brief moment last winter when I watched all of season one of Say Yes to the Dress: Bridesmaids edition in order to know what on earth my friends picked to be bridesmaids were talking about when they complained about plus ones and the cost of getting their hair done and terrible wedding favors, I'm not a big Say Yes to the Dress aficionado. But given who is in the premiere of the newest season airing Friday night, I might become one.

Jillian Michaels, that's who! She shows up as surprise during a fitting for Tumi Oguntala, whom Michaels trained during season 15 of The Biggest Loser. Oguntala is unsurprisingly touched, but perhaps not as much as the store clerk helping them find a dress who says (in a heavy New York accent), "In all my 20 years working at Kleinfelds, I never witnessed something so emotional."
