Williams beat John Higgins 18-16 in the Betfred World Championship final in Sheffield.
But before the tournament started, he vowed to do his winning press conference starkers if he won.
And true to his word, Williams turned up in just a towel to speak to the world’s media.
Williams said: “I’ll do it, I’ll have to, providing Barry Hearn doesn’t discipline me for it!
“Last year I wasn’t even here (he lost in qualifying). Last year I watched this in a caravan having some beers. I just can’t believe it.
“You have to expect a comeback from John Higgins, when you are 50-60 in front he is the best at coming back.
“I knew at the end if I didn’t get enough in front he would clear up again but I’m over the moon.
“Last year I was seriously thinking of giving up, she (wife Joanne) said I can’t sleep in the house 24 hours a day.
“I made a really good break under pressure. My game is now in pretty good shape now.”
Despite losing out to Williams, runnder-up Higgins hailed his competitor’s compsure throughout the last frame.
“It was unbelievable to play in front of this crowd,” Higgins said.
“The last frame was just a joke there for him to play that well under that pressure.
“It is one of the best breaks under pressure that I’ve ever seen.
“Today I was 13-7 behind and I was worried if I would take it to the fourth session, I didn’t want to lose with a session to spare.
“It was a good match to watch but obviously I’m disappointed. He is a great champion.”
