Davina McCall will host part of tomorrow's live show from inside the Big Brother 11 house.

The presenter will join the housemates as part of their current 'Ignore the Obvious' task, but the contestants will have to carry on as normal to avoid incurring a fail.

Visitors to the house have so far included a brass band, a male stripper, Mario's grandfather, zombies and the voice of Big Brother Marcus Bentley.

However, the housemates will face their biggest test when Davina pops into the compound to introduce the latest show highlights and eviction news.

X Factor duo Jedward will also be entering the house tomorrow to perform their new single 'All The Small Things' in the garden.

The Grimes brothers said: "We are really excited to be playing our new single in the Big Brother house. The housemates have been doing really well at this task but we are going to make it really hard for them to ignore us."
