Only James Blunt, Lisa Wilkinson and Hamish and Andy fessed up to plans to let loose at the notoriously booze-filled and fancy-free Logies after-parties on Sunday night at the Crown Palladium, Melbourne.

The British singer told Fairfax Media on the red carpet that following his performance of new song, Don't Give Me Those Eyes, he could let his hair down and would pull an all-nighter.

"I'm British, I'm a professional drinker myself, I just do music as a hobby," he laughed.

"I intend to go straight from the after-party to a radio show at 5am. That is what jet lag is for. It will be most interesting to see how I fare at that tomorrow."

While Channel Nine's Today show host Karl Stefanovic is the one typically known for his roguish behaviour, it is his co-host Wilkinson who said she would be following suit.

"Of course I'm going wild tonight," she laughed. "I'm a mother of three over the age of 50, how often do your reckon I get the chance to dance all night long? That is exactly what I'll be doing tonight."

Although Wilkinson is on-air from 6am on Monday when the Today show will broadcast live from Crown Palladium's foyer, she said there will be "no sleep".

"There's no point in going to sleep. If I go to sleep and I get two hours and I will wake up and think, 'Damn it, I haven't had enough sleep.'

"If I keep punching through, the second wind will come and I'll have a huge smile on my face from dancing with James Blunt hopefully, because he is coming to the Channel Nine after-party," she explained.

But there's no fear of her appearing on-air drunk like Stefanovic did in 2009.

"I'm not much of a drinker, so I can do it," she said.

When asked if they were told to be on their best behaviour by Nine bosses, she laughed: "No, I'm not the one that needs to be told that. You got the wrong person, girlfriend."

Even though she's not on-air until three hours after Wilkinson, Today Extra's Sonia Kruger said she wouldn't be imitating her colleague.

"I have to be up at 5am, that's why I headed out last night," she laughed.

It was no surprise that Hamish Blake and Andy Lee were out for a good night. The pair said they would not rule out the possibility of getting "naked and drunk" to celebrate the announcement of their new television show, True Story.

"It has been two years in the making and we finally get to announce it tonight," Lee explained.

Erring on the side of caution was Nine News' Amber Sherlock's plan.

"I don't think I will get too boozy. I have two small children that I am returning home to tomorrow, but I'll have a few champagnes. I'll have some fun," she said.

Her main concern at the end of the night: "I've been sewn into my dress, so I have no idea how I am going to take it off."
