The 24-year-old came under fire once again in a particularly  explosive row, which escalated after Rex rubbed pizza on Jen's portrait of Stu.

It ended when Dennis spat in Mohamed's face and was later booted from the house.

And he incurred the wrath of Rebecca, too, after implying she was fat and shouldn't eat a batch of cookies he had baked.

All of the arguing and gossiping infuriated Rex, and he even  threatened to walk out of Britain's most famous house.

But after a long and sleepless night, he decided he couldn't quit the game - and would stick it out until the very end.

And it was this determined attitude that helped the house win so many of their tasks.

After Rachel sprained her finger in the OK Go treadmill task, Rex volunteered to step in and learn the complicated routine at the very last minute, memorising it and performing it with gusto.
