Last night on Jimmy Kimmel Live, some self-loving celebrities read — and, even more amusingly, reacted to — mean tweets about themselves. Justin Bieber went blank; Matt LeBlanc cussed; Kristen Stewart grabbed her imaginary balls; and Danny McBride agreeably (at first) swallowed Kenny Powers’s own medicine. Plus: Aaron Paul revealed how that Ciroc commercial with P. Diddy came to be — a random phone call from an obsessed Breaking Bad fan (Diddy) led to the taped bacchanal in Las Vegas. Zach Galifianakis, fueled by peyote, constructed a teepee, only to conclude, after the seven-hour project, there really wasn’t much to do inside. (FYI: his canary-yellow suit was meant to channel David Letterman’s bandleader, Paul Shaffer.) Also, in a throwback to a decade ago, Nelly — sans grills, plus glasses — performed “Hot in Herre” in a promotional stint for the CW’s The Next: Fame Is at Your Doorstep.
