The joint was jumping at Michael’s today with a slew of PR mavens, moguls (Barry Diller) and talking heads (Greg Kelly). I was glad I got there early for my ‘Lunch’ with Dr. Robi Ludwig, who was fêted last night by Bella Magazine at Mamo in Soho in celebration of her new book, Your Best Age is Now (HarperOne). I first met Robi, one of television’s most popular and respected psychotherapists and a regular contributor for Investigation Discovery’s Scorned (“No one loves to talk about murder more than me!”), when she was one of Nancy Grace’s favorite guests on her HLN show and I was writing Nancy’s book, Objection! Let’s just say we’ve always had plenty to talk about. Robi always introduces me to interesting women and today was no exception. She invited publishing consultant Nancy Hancock, who acquired Robi’s book when she was an editor at HarperOne and former QVC host-turned-Nutrisystem pitchwoman Kathy Levine to join us. Between Robi’s new book, Kathy’s stories of working with the late, great Joan Rivers and Nancy’s take on the current climate in book publishing, we covered plenty of ground.
