The pair secured the prize after winning yesterday's task, involving a relay race through golden syrup to find four team-coloured teddy bears which were hidden in pillows on a giant bed.
The pink team, consisting of Cocozza and McLean, finished the task in 11 minutes 33 seconds, while green team members Romeo Dunn and Denise Welch came last with a time of 27 minutes 40 seconds, meaning they will be punished.
They must spend tonight together in the small task room, which will be all white with one single bed. Big Brother will play a soundtrack of Michael Madsen's snoring on loop.
The Yellow team - Karissa and Kristina Shannon and Georgia Salpa - was second with a time of 12 minutes 7 seconds, followed by the Red team Michael Madsen and Kirk Norcross, who came in at 12 minutes 11 seconds.
The blue team Gareth Thomas and Natalie Cassidy finished the task just three seconds ahead of the losers.
Welch and Cassidy found the task particularly hard, with Thomas helping the former find her final bear.
