The former King of the Jungle, who's currently the ambassador to Mr Kipling's Christmas cakes, said: "I must say I've really enjoyed it this year, but I don't like the Chelsea boy Hugo [Taylor].
"I find him irritating and I think Rosemary was quite right to say the things she did about him being spoilt because he's deeply dull and I'm amazed he's got a girlfriend.
On the reality TV show Hugo came from, Made In Chelsea, he said: "I've never seen the Chelsea show. I hate those programmes and the TOWIE one too. I don't understand them.
"Boring people talking about their lives? I may as well go and speak to the neighbours. I don't want to see it on TV! It's a waste of space.
"Reality drama is dull - and they're all so dull. Everyone of them. They're all in their own little lives and they're either bimbos or male 'hunks' - they're not in anyway interesting.
"God knows what Hugo thinks he's going to do after the show. He's just a jumped-up nobody."
But Biggins did favour one member of the camp: "I was very, very sad to see Rosemary go last night. I was dying for her to win and I really wanted her to do the water challenge the last five contestants do.
"When we did it, there was 5,000 torrents of water, hose pipes, wind machines, all sorts of things and suddenly, I turned round and saw Golum coming up behind me in this torrential rain – it was Janice Dickinson!
"It was absolutely hysterical. I have never laughed so much or enjoyed anything so much. I would have loved to see Rosemary do that.
"In the bath tub yesterday. It was hysterical. She was gorgeous!
"Janice thought she was going to win the series and she wasn't happy at all that she didn't. She didn't realise - a bit like Helen [Flanagan] - that people were voting for her to do trials because they weren't liking her.
"When Helen was voted out her face was a picture! She was in shock more than anyone.
"Helen did make me laugh. I don't think she's all there. I read she's now on the verge of a nervous breakdown like Brian Conley. It was interesting she didn't do the interviews like they normally do after being voted out."
Speaking about the show, he said: "I do think all these gameshows are becoming like the Roman games where they are all dying for a death. They won't be happy until someone dies.
"The very first year it was a walk in the park - or jungle. Our particular year was tough - but four years on I don't think I could do it. They're pushing all the time because everyone likes to see people suffer.
"What they need in the jungle is a Kipling machine like we've got across the country, with the Salvation Army singing Christmas songs at them and the smell of cake coming out of them!"

On a potential winner, he said: "I think it's between Ashley or David – and I'd like it to be Ashley. I think she's feisty, funny and I love her laugh.
"She's really being herself and it's time for a queen. I would have loved Rosemary to win but nevermind."
Biggins added of the reality show: "I love I'm a Celeb. I think it's the classiest TV reality show there is. Ant and Dec are brilliant and it's a great show - I just wonder how they're going to push the boundaries next year and I just urge them to be careful."

But he isn't too keen on its sister show, ITV2's I'm a Celebrity, Get Me Out of Here Now, saying: "I can't bear that programme… I think they're all common people talking rubbish!"
