The singer revealed this week that his wife and family were "buzzing" ahead of Friday night's first live show.
However not all of Nicky's close relatives have been as supportive!
"My wife [Georgia] is buzzing with excitement. She will come to all the shows — we are very much a team," he said today. "Her sister, Cecelia, nicknamed me Glitterballs and now that’s the running joke in my family.
“I like to put a smile on their faces.”
And it sounds as though Nicky certainly did that from the first live show.
He told The Sun this morning: “After seeing my first dance, Georgina could not stop laughing for ten minutes “She told me, ‘Seriously, you need to change your style’.
“And when I watched myself afterwards, I was like, ‘Oh no!’ I had Cuban heels with ankle socks and shorts! My legs looked so white. I am not sure I am ready for fake tan yet but everyone tells me the wall does come down eventually.
“I guess a lick of paint is not the worst thing in the world.”
Speaking about his professional partner, hot US dancer Karen Hauer, Nicky added: "Karen is great. She is patient but she is no walkover either.
“She won’t let me sit and have a coffee. I am putting in five hours of training every day. But I love it.”
The Strictly Come Dancing live shows start on Friday night on BBC One.
