Tulisa was always very vocal about supporting James on the show, although it seemed more about stopping Chris winning than anything else.
Asked if she was hoping to collaborate with James, Tulisa told Yahoo! omg: "Hell yeah. He's so so talented and such a star."
Revealing the advice she had given to the singer, Tulisa added: " To keep doing him, don't let any one change you. Keep being James then he can't go wrong"
And the 'Young' hitmaker claimed there had been quite a lot of partying after the final, although she was a good girl, for once!
"Oh a lot, I was one of the good ones though; I left everyone in the bar at 1am," she told the website.
Meanwhile, Tulisa joked she was "quite looking forward" to ditching the thousand pound dresses from the live shows and relaxing back in her tracksuit.
James' winner's single Impossible is out now to download and has already sold more than 255,000 copies, making it the fastest selling winner's single from an X Factor act ever, and by far the fastest selling single of this year.
