Joan Rivers' Doc Not Authorized to Work at Clinic

Citing multiple sources, TMZ has identified Joan Rivers' personal doctor—the one accused of doing an unplanned biopsy and taking a selfie during Rivers' procedure—as Dr. Gwen Korovin, who boasts other celebrity patients, including Celine Dion and Lady Gaga. According to the gossip site, Korovin was the one working on Rivers when she stopped breathing, but the doctor was not authorized to practice medicine at the Yorkville Endoscopy center where the procedure took place. Since then, she's been keeping out of the spotlight. "Everyone close to Joan thinks Dr. Korovin skipped town," a source tells Radar. "Joan's daughter Melissa has been telling friends that she is a spineless monster." In other Rivers news:

• She reportedly left her $150 million fortune to daughter Melissa, grandson Cooper, and her four dogs. "Those dogs are her family," a friend tells the New York Daily News. "They meant the world to her and Joan wanted to make sure that if anything happened to her that they would be taken care of." The dogs will move in with Rivers' longtime assistant and friend.
• Rivers fans will want to tune in to E! tomorrow for "Joan Day," an all-day marathon featuring back-to-back episodes of Fashion Police. Melissa will also host a 90-minute special remembering her mom, which will feature behind-the-scenes and unaired footage, including outtakes.
• Melissa Rivers also spoke publicly for the first time since her mom's funeral, People reports. In a WhoSay post, she writes, "My mother would have been overwhelmed by the scope and depth of the love that people have expressed for her."
