Patti LaBelle's book signing Tuesday was crashed by anti-fur protesters, TMZ reports. LaBelle was signing copies of her "Desserts LaBelle" book at a Barnes & Noble when protesters posing as fans asked for a group photo. When LaBelle obliged, they pulled out signs and began chanting, "Patti LaBelle has blood on her hands. "It's similar to what happened to Kelly Rowland in New Jersey earlier this month, and to Kylie Jenner last weekend in Las Vegas.
