A few days before tonight’s Late Night hosting debut, Seth Meyers catapulted  TLC‘s Say Yes To The Dress to its most watched season debut ever, according to Nielsen numbers out today. An average Say-Yes-to-the-Dress-350x230of 1.6 million viewers caught the Season 11 opener on Friday, in which Meyers surprised a fan, bride-to-be Shealynn who was injured in a roadside bomb blast in Afghanistan while serving as an Army medic.  The season kick-off clocked the show’s second best opening numbers with  women 18-34 and 18-49 and it was No. 1 in its Friday timeslot among all ad-supported cable among women 18-34. Meyers was seen surprising her at the end of her Kleinfeld dress-shopping appointment. Meyers is the latest celeb cameo for the TLC reality series — a list includes Kristin Chenoweth and Kelly Ripa.
