The `Rockstar` singer insists he has cleaned up his act now for the sake of his sons Gino, three, and 14-month-old Milo - his kids with girlfriend Kaye Vassell - but is glad he has had the experiences he has. He said: "I was never doing drugs to Amy Winehouse`s extent but I could`ve really gone downhill. I could`ve easily stayed on drugs because I`ve got the money. "Of course I`m not [still taking drugs]. I`m fresh and I`m clean. I`ve got two kids. But if I had none of that past, I`d find myself boring. What would I have to rap about?" Dappy also insisted he is now faithful to Kaye because he didn`t like the "stress" of trying to win her back following his dalliances with other women. The N-Dubz star told Now magazine: "I`ve made mistakes. I`ve cheated. All it does is make you look like a weak person, like you`re desperate to get more women because you need more attention. If I just gave myself to everyone, I`d lose my mystique - you can`t be available to f**k every Tom, Dick and Harry.
