The two reality shows have been regularly going head to head nightly over the past month or so, with revamped Love Island having beaten long running Big Brother recently.
It's quite a turnaround: Back in 2005 and 2006, Big Brother's huge viewing figures crushed the then celebrity-based series of Love Island when it was on ITV and arguably led to its axe.

In a VT on last night's (Saturday) Love Island recap show, narrator Iain Stirling made a quip when he introduced a joke reality show featuring Kady McDermot, remarking the the programme will air on "some obscure station no one ever watches... Channel 5."
While Love Island has enjoyed some wins over Big Brother in the daily ratings, the Channel 5 series still comes out a clear winner on average.
And in fact, the latest series of BBUK is on course to be up on last summer's show, with an average audience of 1.6 million in the official figures.
Both Love Island and Big Brother air tonight at 9PM on ITV2 and Channel 5 respectively.
