Nicky Byrne has confessed the pressure is on as he kicks off his Strictly Come Dancing training alone.
The Westlife singer admitted this week that he felt "totally exposed" when on the dancefloor for the first time for Saturday night's launch show.
Speaking to DigitalSpy, Nicky said: "When I walked on the floor I thought, 'Holy s**t, what have I signed up for?'
"You are totally exposed and this is the first time I've done something out of Westlife."
Nicky claimed that Strictly was one of the "toughest" reality shows around.
He told the website: "This is something with such media interest and out of my comfort zone, it's the toughest thing I could have picked."
However he added: "It's actually a long while since I've done something like this where I'm genuinely excited about what I've got in store during the day.
"All the celebrities are riding a crest of the wave at the moment."
Tweeting from training, Nicky's professional dancer Karen Hauer indicated that rehearsals were going rather slow
She joked: "Day 2 of training : finished: Nicky was actually wearing trousers instead of shorts = progress"
The Strictly Come Dancing live shows start on October 5 on BBC One.
