Fading Playgirl pin-up Levi Johnston is still clinging to his 15 minutes. The puck-loving Alaskan was recently spotted tagging along with reality show star Kathy Griffin during a signing of her new book, “Official Book Club Selection,” at a Borders in Anchorage. A camera crew for Griffin’s Bravo show, “My Life on the D-List,” was also spotted outside Sarah Palin‘s home in Wasilla. On Tuesday, Johnston was ordered by a judge to fork over $21,000 in child support to Palin’s daughter, Bristol.
