The interior designer got the least votes from the public.
Colin, 41, looked gutted as he had to say an emotional farewell to his partner and fellow camper Justin Ryan.
'Justin and I have lived together for over 20 years and we have our own world and our own way of doing things,' he said as he left the jungle.
'Within a few days people started to take on their own roles and community happens - it was incredible. We've shared every single other life adventure that we've had.
'The whole bittersweet thing, the fact Justin's not here now - that we can't talk about what's happened - is really quite sad.'
Ex-EastEnder Lucy Benjamin, 39, was the first contestant to be voted off the ITV show on Monday.
