[Mickey2009]

This morning it was announced that for the new Shopping Task, housemates had been transported to the Big Brother House of 2209. And in the open-minded 23rd century, even aliens are allowed to enter the House.

And seemingly, they're also allowed to leave it to do a little sight-seeing.

Dressed as aliens, Lisa and David have today been on an open-top bus tour of London. They've been to three landmarks - Tower Bridge, St Paul's Cathedral and the Houses of Parliament.

To pass their part of the Task they were instructed to get a photo of themselves taken by another tourist on the disposable cameras given to them by Big Brother. However, they were not allowed to talk to anyone except for each other, and they only had 10 minutes at each landmark.

They've had an exciting day out on Planet Earth, but like any good extra-terrestrials, eventually they had to go home.

And when they arrived back this evening the pair looked pleased as punch after their grand day out.

"I can't believe it," Lisa beamed as the pair chuckled together.

But did they get good holiday snaps
