The TV cook split from husband Charles Saatchi last year after images emerged showing the businessman apparently throttling his wife outside a London restaurant.Lawson subsequently endured a harsh examination of her life during a court battle involving the couple's former assistants, during which she was forced to admit taking cocaine.Speaking with chat show host Michael McIntyre, Lawson wiped tears from her face as she discussed finding a new home and moving on after the highly-public split.She says: "I've had better times. You know it's spring and I'm feeling better and I'm very happy to be here... I've been alive longer than you so I know that... life has its dips and it can get better, you can't fight it."Discussing the media storm that surrounded the court trial that made her past drug use public, the former journalist adds: "I'm not an innocent, I understand how it works, I just don't involve myself. I don't speak and I don't comment."I could say things and they would be indiscreet but I don't want to. The real truth is that if you don't read things and you don't get too involved it doesn't enter your bloodstream, if it doesn't enter your bloodstream you don't get contaminated..."We all gossip but I don't take a particular lofty view, perhaps having a layer of skin removed I'm also more aware of other people's misfortunes."
