From Page Six:
Rival Inside Tinsley's Gates
THE battle between self-titled It Girl Tinsley Mortimer and socialite wannabe Olivia Palermo is heating up now that Palermo has a spy in her rival's camp. Peter Davis, Tinsley's best friend and brother-in-law, has become close with stylist Kristian Laliberte, Olivia's best friend, according to parkavenuepeerage.com - a development that's infuriated Tinsley and hubby Topper. The two women are in a vicious struggle to reign over New York social life, and Tinsley recently made it physical when she elbowed Olivia to the ground during a fashion show. Meanwhile, Tinsley flew to Japan last weekend wearing a kimono on the plane, our spy giggled, to promote her own line of handbags, since she was recently dumped by handbag queen Samantha Thavasa - and p.r. guru Paul Wilmot - for being too demanding.
