Kelly Osbourne is going through a rough time after her split from her ex-fiance, Matthew Mosshart. The 'Fashion Police Star' has reportedly put herself in "food rehab" after gaining weight as a result of the breakup four months ago. 

UK's Now Magazine reports that Osbourne had gained almost 20 pounds since she split with Mosshart. Mosshart, a vegan chef, reportedly encouraged Osbourne during their time together to adopt healthy eating habits. As part of her rehab, Osbourne will be undergoing a strict weight loss regime. In addition to better eating, the 29-year-old has also signed up for yoga and Pilates with a private instructor for five days a week.

Osbourne has reportedly been seeing Braydon Szafranski but tells the Daily Mail that she doesn't plan on jumping into a serious relationship just yet. "I plan on being single for a very, very long time. No, I don’t think it’s possible for someone to sweep me off my feet right now. I’m really enjoying my life."

We wish Kelly the very best and hope she reaches her goals for a happy and healthy life.
