He's the popular late night host who's always willing to go there.

But Last Week Tonight host John Oliver might be taking things to an entirely new level - with speculation mounting that he bought Russell Crowe's used jockstrap.

Last month, the UK-born late night host showed interest in the item, even teasing that he would bid on it when speaking about the Oscar winner's 'divorce auction.'

Would I be stupid enough to buy it? Speculation is mounting it was comedian John Oliver who purchased the jockstrap Russell Crowe wore on Cinderella Man, which sold at his 'divorce auction' on Saturday for $7000

John started by introducing the auction, with his signature anti-Trump humour.

'It's called Russell Crowe: The Art of Divorce,' John said on his March 8 show.

He then went on to mention the unusual undergarments, which Russell wore in Cinderella Man, when he played the role of James J. Braddock.

Way above expected price! Last month, John Oliver mentioned the unmentionables by name on his show when speaking about Russell's 'Art of Divorce' auction

'You can buy items such as the leather jockstrap used during the filming of Cinderella Man...Will we be stupid enough to bid on that? I don't know. Why don't you ask one of our five wax presidents?'

Although he left it at that, at auction the item actually outdid it's reserve price by an extraordinary figure, with it expected to fetch around $500 to $600.

It, instead, sold for a whopping $7000, which prompted interest in who purchased the Gladiator star's unmentionables.

Daily Mail Australia has reached out to John Oliver for comment.

The auction, held in Sydney on Saturday, saw Russell bring in a staggering $3.7 million from the items he auctioned off.

It included a number of celebrity buyers including British TV personality and MailOnline columnist Piers Morgan - who purchased two sporting jerseys.

Speaking to Daily Mail Australia, the 53-year-old presenter said he was determined to acquire the famous auction pieces after scouring the Hollywood star's list.

'Now to be the owner of their personal international jerseys makes me incredibly proud and happy. It's even more special that they came from Russell's private collection as I'm a massive fan of his work as an actor.'

The auction, which featured the sale of movie memorabilia, Australian art, musical instruments, his ex wife's jewellery and cars, saw Crowe net a staggering $3.7million.

The 54-year-old devised the auction as a way to deal with the end of his nine-year marriage to Danielle - following their separation in 2012 - and to clear out 'stuff'.

'In case anyone is interested ... $3.7m at the coal face and around $350k of conversations ongoing ... and a bunch of stuff I didn't really want to sell coming home ... not a bad hourly rate for a five hour shift . Hope you are happy and busy,' Crowe wrote on Twitter after the event.

Heroes: 'When I went through the list of auctions items, I realised there were two I just had to have. Shane is the greatest bowler of all time, and Jonah was the greatest rugby player of all time,' Piers said (Pictured is the Jonah Lomu jersey)
