Kelly Cutrone axed her smug assistant, Andrew Mukamal, when his stint on Bravo’s “Kell on Earth” made him too big of a star to do her dirty work and grab her a coffee, she claims. “He cared more about being a TV personality than being my assistant,” a curt Cutrone told us. The sharp-tongued publicist claimed Mukamal was distributing photos of himself in front of her fashion p.r. company’s logo, People’s Revolution, with statements about what he was wearing. “Just because you worked as an assistant in the fashion industry doesn’t make you an expert,” she snapped. Mukamal, who has pitched his own reality show to E!, responded, “no comment.”
