There was a task! The housemates were given a chance to join Jade and co. in the lap of luxury, but first they had to arm wrestle, smash eggs on their heads and drink some foul-looking liquid. Worth it! Jack pulled wax strips from his legs

After the eviction Jade had to pick a HM and she picked Joel

Joel was picked to join them yesterday HLs morning

The other during one of the tasks in yesterdays HLs

Aha, cheers me dears
