The Australian cricketer-turned-chatshow host, who was recently romantically linked to Elizabeth Hurley, said that his youthful appearance is purely due to moisturisers, healthy eating and exercise.
Warne wrote on his Twitter page: "Questions re facelift/Botox etc are absolute rubbish. I am 86kg. Lost 7kg and close to being the fittest I have ever been. Fitness and being healthy is now a daily habit I feel great and never been happier in my life.
"I am also eating very healthily and am flattered that people think I look younger. I have worked hard over the last five months on fitness. New Estee Lauder moisturisers for my skin have made a big difference. Yes, I'm still a man."
Warne was first connected to Hurley in December last year, shortly before she announced the end of her marriage to Arun Nayer. The sports star later revealed that he was no longer with his wife Simone Callahan.
Hurley and Warne were believed to have split following his alleged involvement with a porn star during their relationship, but the pair exchanged tweets over the weekend.
