TODAY host Karl Stefanovic has slammed the Daily Mail for "sexist" reporting, saying the news website has a "long, despicable track record of denigrating women".

It comes after the publication posted an article about him last night showing him carrying cans of pre-mixed rum and claiming he had checked into a "humble caravan park" with a Channel Nine colleague, and without his girlfriend.

"The inference ... I'm a drunk. The real hurt here though is for my colleague, a young, female colleague. The sleazy suggestion we're 'checking in' somewhere and that I'm - quote - 'settling in for a long night'," he said.

"The producer pictured on the website is a committed, talented, hard-working and totally professional young woman - and not deserving of this cheap, lazy, sexist online slur.

"(She's) a young woman who's spent the past few hours in tears because of the hurtful and false way she's been portrayed by this website.

"The idea that colleagues of the opposite sex cannot work together without 'something going on' surely belongs to the 1950s. And for most of Australia, it does. But not, it seems, on this website," he said.

"This is the site that ridiculed Lisa for wearing the same blouse four months apart. The same site that tried to suggest that Lisa and Sylvia couldn't work together - presumably because they're both women," he said.

"The same site that tried to shame Sunrise host Samantha Armytage for wearing so-called 'granny pants'. I’m over it. And I don't know but I think and hope Australia in 2017 is over it.

"Go hard on me. Make up your stories. Publish your lies. Send out your paparazzi. But if you have a sliver of decency, if you have any care whatsoever for the women of Australia, do not slur the reputations of others in your eagerness to throw mud at me."

Stefanovic ended his monologue by calling on those who agree with him to "never go to that website".

Channel Nine colleagues and other journalists have flocked to rally their support for Stefanovic on social media.

Late last year the Daily Mail was forced to make an apology to Sunrise host Samantha Armytage over the story about her “granny panties” showing through her dress.

The bottom of the article was amended with a small statement apologising for “any distress caused to Ms Armytage or readers more generally”.
