Secret mission for the first four

Mario, Lisa, Luke & Stephanie were the first four housemates to enter the new BB house, and as soon as they were in, they were all called to the diary room for a secret task!

So Mario & Lisa are the first ever couple to hit the hosue going in - but they've now got to keep that under wraps - in fact, as part of the task, Mario & Stephanie have to pretend to be a couple for all the other housemates.

If the four of them can keep this secret, and the rest of the housemates fall for it, then they'll be saved from the public vote next week!

If not, they'll be up for the chop...

Oh yeah, and Mario & Stephanie will be getting married this weekend. And they'll think it's for real. He's a lucky boy...
