Rex's girlfriend takes part in task

Rex's girlfriend and Mohamed's brother joined an identity parade in the house tonight as part of this week's shopping task.

Luke and Lisa entered the task room to face a lineup of pretend criminals.

The duo were told by Big Brother that one of the strangers was Rex's girlfriend and that they had 30 seconds to decide which "criminal" she was.

Numbers three and six were considered as potentials, but the pair eventually opted for the latter.

Big Brother then announced that Mohamed's brother was also among the lineup, and Lisa and Luke were again asked to give a number.

Giggling and talking over their decisions in the garden, they agreed that they would tell the group what had happened.

"He is going to flip," said Luke, talking about Rex.
