Preparing to compete in her first challenge, Washington declared that she had been "dying to do one". The two were then told by Ant and Dec that the trial was called Buzz Off, with Manning having to direct Washington from a hive while she navigated her way across an assault course to release the stars.
Attached to the former Mis-Teeq singer's helmet were two antenna that she had to avoid touch aligning the copper rail. If they connected, Manning would receive an electric shock. If she touched the rail three times, they would lose the star and have to move on to the next.
The pair got off to a bad start, Washington only taking a few steps before hitting the rail three times, causing a trio of shocks for the actor. "Man those electric shocks hurt!" he said.
Getting into her stride, she narrowly missed the second star and touched the rail for a third time. A disappointed Washington stated: "I'm scared to even move my legs. This is so bloody hard."
Having reached the fourth section, she successfully navigated a star and won two meals for camp. During the last part, she was distracted after being stung by a wasp and hit the rail three consecutive times. A disgruntled Manning received another three shocks as more green ants rained down on him.
After the task ended, the pair returned to camp and were consoled by their fellow celebrities as they revealed they had only won three meals.
