NBC If you've got it, flaunt it. Right , Milo Ventimiglia ? The actor appears completely naked in the first episode of his upcoming NBC series This Is Us with just a small towel covering his junk. The internet was sent into a tizzy when we got a peek at his firm butt in the launch trailer for the dramedy . As of today, the trailer has been viewed more than 7.3 million times, a record for a new series. "It was one of those things [being on network television] I thought no way and I get to my trailer in the morning on the first day of filming and I look at my choices of wardrobe and it's really not much," Ventimiglia told me last night at the Hollywood Foreign Press Association's Grants Gala at the Beverly Wilshire.
