The 68-year-old continues to act as Lord Sugar's right-hand man on the new series, and admits that even after eight years on the show, he doesn't realise how much he frowns!
Speaking to The Sun today, Nick explained: "I've got a very mobile face and I think the cameramen pick up on it."
And he joked: "I'm thinking I might have Botox to make it impossible to raise my eyebrows."
The PR Guru, who is joined once again by Karren Brady on this year's show, went on: "It's not like I practise it in the mirror. No one makes me raise my eyebrows on cue. I am what I am.
"Nobody would have the nerve to ask me to do something to suit the cameras and there are no retakes."
Meanwhile Nick insisted that neither he nor Karren ever know what will happen in the boardroom, following two surprise exits this year already.
He said: "We never know who he is going to fire right up until the very moment he does it."
