American musician Ray J left the house today after one week in the house, having reportedly scooped Celebrity Big Brother's biggest EVER fee.
Singer Ray J previously dated Kim Kardashian and back in 2007 appeared in a leaked sex tape with her that hit the internet.
Show bosses were reportedly in talks to get Ray - who is cousin to fellow music star Snoop Dogg - to appear on Celebrity Big Brother for a while.
According to TMZ, Ray's deal was worth a cool $1 million which works out just over £800,000 at the time of writing.
In addition, he had apparently also been given a $30,000 allowance for flights and hotels while in the UK.
Celebrity Big Brother 2017 continues nightly on Channel 5.
