Gwyneth Paltrow's close friend and personal trainer Tracy Anderson has split from her husband of two years. The celebrity fitness guru, who has also worked with Madonna, Jennifer Lopez, Jennifer Aniston and Nicole Richie, wed Matt Mogol in 2011, but the couple has now parted ways. Her representative tells UsMagazine.com, "It's with great sadness that Tracy has confirmed the separation between herself and her husband, Matt. "The well-being of the daughter that they share, as well as her son, will always remain Tracy's first priority. "We appreciate the respect of Tracy and her family's privacy during this immensely heartbreaking and painful time." Anderson and Mogol are parents to one-year-old daughter Penelope, while the trainer also has a 13-year-old son from her first marriage to former basketball star Eric Anderson.
