Bobby Sabel has been causing trouble in the Celebrity Big Brother house – by secretly getting photo agency boss Darryn Lyons to drink his sweat.

The model – who is up for eviction with Kerry Katona and Sally Bercow – played the prank during a Wizard Of Oz task, where the housemates took the roles of characters from the famous story.

With Darryn dressed as the Tin Man, Bobby filled a watering can for him to drink from – whenever he needed oiling’ – with a mixture of lemonade and his own sweat.

We greased him good,’ boasted Bobby, 25, after the incident.

Later Bobby had a change of heart and confessed his antics to a shocked Darryn, 46.

I did something stupid earlier,’ admitted the good-looking contestant.

The last couple of days I hated you and I took it too far today.

That watering can, there was lemonade and sweat in there.

You’re a good guy, but in this environment we clash.’

Australian paparazzo Darryn – who was offended at being nominated for the Tin Man role due to fellow housemates believing he didn’t have a heart – accepted the apology.
