How are you feeling, David?
"I feel great. I was almost King of the Jungle! To be honest, I'm happy to be booted out. I was the last man standing and I'm happy with that. I lost out to two wonderful girls. In my eyes, they are both Queens of the Jungle."
What exactly do you think of Ashley Roberts?
"Ashley is amazing. For someone to come from obscurity to this is amazing. She doesn't need four other Pussycat Doll bandmates; she can do it all off her own back now. Americans don't normally work well on these shows, but she's broken the mould. It's an amazing achievement."
What was she like as a campmate?
"Ashley was fantastic. She was always doing her yoga every day. She's very, very positive - but not in an annoying way. She's chilled, but she would switch it on when she needed to."
What do you think of Charlie Brooks?
"Charlie is a fantastic mother and she really struggled in the jungle with the lack of communication with her daughter Kiki. She was continuously talking about her baby."
How upset was Charlie when she discovered that her daughter had been brought into the jungle for a challenge, but then whisked away without seeing her mother?
"At first, Charlie was unaware that Kiki had been in the jungle. If I hadn't opened the door to my mother and told Charlie that our friends and family were there, she wouldn't have known about it. She was completely unaware of the possibility that her daughter could be put in that position."
How did Charlie react to the news?
"She felt genuinely guilty about it. She was cut up. She doesn't mind her own feelings being hurt, but it was unfair to put that on Kiki. I thought that was a real harsh game to play. That was close to the bone. I can understand putting Charlie through some sort of mental torment because she's getting paid for it. She knows it's a game, but the fact that her daughter was brought into it left a bad taste in her mouth."
What did Charlie say about the incident?
"Charlie was really upset. She went in and had a word with them [the producers]. She said that they needed to guarantee that her daughter was okay. She was pretty angry, too."
Was Charlie angry enough to think about quitting the show?
"I'm not sure if she was close to walking, but I had a chat with her about it. We said that the challenge was maybe a little harsh, but the best thing she could do was grit her teeth and give the best shot she could at winning. She knew her daughter was safe and she won a letter from her the next day, which made Charlie happy again."
There's a jungle rumour that you want to become an actor now... Is that true?
"That's very true. I've been acting my whole life really. The whole 'Hayemaker' boxing persona is an act in itself and I've sold it to many people. Some people love me for it, some people hate me for it - but people feel passionate about it in one way or another. One thing they didn't realise was the fact that I was acting."
What would be your dream role?
"A dream role for me would be an evil villain. I've always wanted to play the bad guy, so I'd love to be a Bond villain. Javier Bardem was amazing in the last Bond movie. He absolutely stole the show as the most evil guy in the world. He was superb. I'd love to play something like that."
Does this mean you'll be heading to Hollywood soon?
"I'd love to go to Hollywood. If I had to move there to get the roles I want, then I'd be more than happy to make the move. To get to where you want to get in life, you've got to make sacrifices and changes. To get to where you want to go in life, you've got to roll with the punches."
Who is your acting icon?
"The Rock - aka wrestler-turned-actor Dwayne Johnson - is a huge icon for me. I was a big fan of his when he was in the WWF. I thought he was a great wrestler. He's a great all-round entertainer. He sings, dances, wrestles, acts... He can do it all and he looks the part as well."
Do you rate his acting skills?
"I think he's a really underrated actor. He's played so many different roles, but he nails each and every one of them. For me, what he's done with his career is outstanding. He's gone from the pinnacle of one sport to the pinnacle of another art altogether. He's a believable actor now. He's crossed over fully. In fact, there are people who don't know he was a wrestler before; they think he's been an actor all along."
How much weight did you lose in the jungle?
"I lost six kilos in the jungle. I knew I was going to lose weight. They told me the scenario about the food deprivation before I signed up to the show. I knew I was going to have a lack of calories, so I treated it as a kind of detox."
Were you worried about the effect of the jungle on your body?
"I was fine. From time to time, it's good to shock your body. I'm used to eating large volumes of food five or six times a day during my heavy training - but I haven't really had that much time off from it. It was nice to have a period of three weeks where I could flush out my system. Now, my skin's gone really clear too. I've seen pictures of myself and I think I look in good condition."
Are you worried about the loss of muscle?
"Muscle is muscle. You can put muscle back on. You can bulk up. Naturally, I'm not a big guy. In fact, I eat my way up to heavyweight. Naturally, I'm around 90 kilos. That's the weight I'd be if I'd done no training. But the guys I'm fighting are 115 kilos or more. I have to stuff myself to get up to 96, 97 or 98 kilos. I think I was 95 kilos for my last fight and I need to eat so much to keep that up."
Are you concerned about how you're going to put the muscle back on?
"I'm not worried about that. I know my body really well and I know the kind of food I have to eat to get it back. I also know the exercise I'll have to do to get it back. I'll be fine."
