Michael Weatherly has a mischievous side and demonstrated it by drawing horns on his TV Guide Magazine cover photo, then proclaiming proudly that “it’s now worth 75 cents.” It was all part of the fun at the chic HGU New York hotel where TV Guide Magazine celebrated Weatherly’s new show Bull and his appearance on the cover of this week’s magazine. The evening’s sponsors included Banfi Wines, Tito’s Vodka, Peroni beer and Baked by Melissa cupcakes.
