The Tangled challenge was the final chance for the stars to free themselves from their handcuffs and receive immunity from eviction.
Each pair had to pass their key along a knotted rope to unlock their rope and then unlock their handcuffs.
Ollie Locke and Lionel Blair were the first to finish and therefore won immunity.
They managed to pass the key over the ropes and unlock their handcuffs in 2.53 minutes.
They join Jim Davidson and Linda Nolan, who won yesterday's (January 4) challenge, and Sam Faiers and and Jasmine Waltz, who came second.
Lee Ryan and Casey Batchelor were second in the Tangled task, followed by Evander Holyfield and Luisa Zissman.
The two pairs will now face the public vote along with Dappy and Liz Jones.
