The 46-year-old paparazzo will have one hour to take 'shock horror' snaps which match five Big Brother news stories.
The headlines Lyons has to find photos for are: 'Get Hoff Me!', 'When Paddy Met Sally', 'Storm in a D-Cup', 'Love is in the Air' and 'Oh Brother Where Are Thou'.
Calling him into the Diary Room, Big Brother told Lyons that the whole house will receive a pap party if he takes three sufficient photos, while he himself will win a personal prize if he is able to match all five headlines.
Lyons, whose camera is disguised as a cigarette packet, has an hour to complete the task.
Watch Darryn Lyons attempt his secret task below:
These Celebrity Big Brother scenes air tomorrow night at 10pm on Channel 5.
