He’s known for his love of high jinx.

And true to form, Today host Karl Stefanovic, 40, had a great time working in New York when he whipped off his tie to party hard with pretty blonde models, Ashley and Jessica Hart.

Opening his shirt to reveal a broad hairy chest, the playful presenter collapsed in a laughing heap between the Australian siblings and 60 Minutes producer, Steven Burling.

Living it up! Today show host Karl Stefanovic, 40, whipped off his tie to party hard with Ashley and Jessica Hart in New York City this week

Guffawing liberally, it was clear the presenter was making the most of not being a slave to his early alarm not going off.

And the feeling was mutual as the younger sister of top model export, Jessica, 29, testified on Instagram.

'Oh what a night!!!!' the bohemian beauty wrote beside a picture capturing the essence of the evening. 'A night with these legends would never be long enough.'

Grabbing life: The Today host whipped off his tie to let his hair down with fellow Australians in New York

Karl, whose seat on the Today Show is being kept warm by David Campbell while he works in NYC, is known for seizing opportunities to let his hair down in between interviewing celebrities and appearing on Channel Nine.

At the 2009 Logies he appeared rosy-cheeked, slurring his words and frequently giggling.

'It wasn’t any different to any other year — we all get smashed at the Logies and go to work the next day; we’d done it for years and years,' he told news.com.au.

'But this was the first Logies when stuff really started working on the internet,' he said.

'I remember seeing it on and going "Oh god" I really was drunk, or at least I certainly looked and sounded drunk.'

At this year's Logies he cuddled up to I’m a Celebrity…get Me Out Of Here star, Chrissie Swan, 41, nestling in close for countless selfies on the red carpet.

Showering each other with kisses on the cheek, the pair ensured they captured their best sides taking snaps from every feasible angle.

Returning the favour! The good mates attempted once again to get the all important picture-perfect selfie

Cheers! Karl was photographed at one of the Logies parties with a drink in hand but said he's feeling better this year than he has in the past

Good mates Karl and Chrissie looked equally keen to get the perfect kissing selfie as they snapped away before showing each other the end results on their iPhones.

The Gold Logie-winning presenter recently admitted he had skinny-dipped at a friend's wedding in Byron Bay with Leila McKinnon on Nine's Today show.

In a segment for the programme's Mixed Grill segment, the subject of a nude beach was raised and Leila confessed: 'I'm in the position where I've already seen Karl naked, so um, it wasn't a big disappointment for me.'

The morning after the night before: Stefanovic was clearly exhausted after partying at the glitzy awards show this year and was seen taking a nap during an ad-break on the Today Show

Shifting in her seat, Shelley Craft looked towards Leila, saying: 'I'm on your side for this one Karl.'

'I can't say too much though because he has seen me naked too,' Leila replied.

After a very awkward silence, Karl went bright red before clarifying the turn of events and insisting it was an innocent situation.

'This could go very badly this conversation, if someone's listening,' he said.

'We were at a friend's wedding and we nuded up and jumped in the ocean... doesn't everybody do that?'

Devoted: The presenter has been married for more than a decade to Cassandra Thorburn and they have three children, Jackson, Ava and River
