A former employee of Lizzie Grubman is suing the legendary lead foot for $6 million. Brenda Loughery claims the PR princess reneged on promises to make her a partner in her company and get her a job on PoweR Girls — Grubman's forthcoming MTV reality show. Grubman's lawyer says his client plans to "vigorously defend" herself. If that's not a euphemism for "hit and run," I don't know what is.
