In Pictures: First look at tonight's Big Brother 2013 highlights

Here's a first look at tonight's Big Brother 2013 house highlights.

It's Day 47 and Big Brother sets the group their new shopping challenge, with help from two professional wrestlers.

This week the housemates have become wrestlers and each have been given an alter ego: There's Dexter the Devious, Strongman Sam, Gina Warrior Princess, twins Jackadore and Jaded Joeker, Hot Shot Hazel, Sophie Slamdown and Cowboy Callum, while Charlie is the referee for the task.

Each of the wrestling housemates have been paired off for separate challenges, which they must complete in order to win the luxury shopping budget.

In tonight's show, rivals Dexter and Callum face a flinch off, as they're teased with all manor of icky objects while having to remain as still and as calm as possible.

Meanwhile, Hazel and Gina get physical in a sticky battle to pin one another to a velcro mat.

In the evening and the tasks may be over, but the rivalries are stronger than ever and things get tense in the house.

Callum and Dexter continue to bicker well into the early hours until eventually both have had enough and declare themselves done with one another.

Big Brother airs tonight at 10PM on Channel 5.
