Nicki Minaj didn't realise she was ''a bit strange'' until she worked on 'American Idol'.

The 'Starships' hitmaker has been bemused by the odd reactions to some of the comments she has made as a judge on the show, insisting she is exactly the same on the panel as she is in real life.

She admitted: ''I guess I didn't realise that maybe I am a bit strange because, like the way people react to what I say to the contestants. It's like, that's really how I act, but people think it's kind of strange.

''Like when I asked Kree [Harrison] to marry me, I didn't think that was strange but I guess looking back at it now, maybe no 'Idol' judge has ever asked a contestant to marry them on live TV.

''I guess in general I'm just surprised at the way people react to things that I see as very normal.''

Nicki is enjoying working on the judging panel - on which she is joined by Keith Urban, Mariah Carey and Randy Jackson - and thinks she is doing a ''spectacular'' job.

Asked for her best and worst moments so far, she said: ''I don't have a worst 'Idol' moment. I've been spectacular. Yes, I'm going to toot my own horn. And then, my best moment is every single moment, I'll toot it again.''

'American Idol' airs on Thursdays and Fridays in the UK at 9pm on 5*
