Celeb trainer Tracy Anderson is separating from her husband of nearly two years, Matt Mogol.

Anderson's rep, confirmed the news, telling Us Weekly: "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."

The couple wed on Sept. 27, 2011, in Big Sur and welcomed a baby daughter, Penelope, in May 2012. Anderson also has a 13-year-old son, Sam, with her first husband, former NBA star Eric Anderson.

Anderson's clients include Gwyneth Paltrow, Jennifer Lopez, Victoria Beckham and Nicole Richie.

The fitness guru and founder of the Tracy Anderson Method is also adapting her techniques for expectant moms with The Pregnancy Project. She is currently creating an exercise program to help Kim Kardashian bounce back after baby. (The reality star and boyfriend Kanye West welcomed North West into the world on June 15.)

"It's a tough time, and a lot of women feel like it's a huge mountain to climb to get back, but Kim, surprisingly, has had the totally opposite reaction to other moms," Anderson said.

"She's like, 'We're going to be so good. It's fun, I feel great!' She just loves the whole process. From our talks during her pregnancy, I thought she was going to be really concerned [about her weight] once the baby was out, but she's just not...She's in baby heaven. She's excited to get started, but she's really calm about it all," Anderson added.
