Nicki Minaj is to star in her own reality TV show.

The 'Starships' hitmaker - who was recently unveiled as a judge on 'American Idol' - is said to have begun filming a fly-on-the-wall documentary series for the E! network earlier this week, gossip blogger Perez Hilton has revealed.

Insiders are convinced the eccentric singer will make for great viewing.

One told the Daily Mirror newspaper: ''Nicki's life on camera will blow away all other previous reality stars.''

Nicki recently revealed she agreed to judge 'American Idol' because it is such a ''credible'' show.

She said: ''This is such a credible brand. It's really serious, it's real deal it's not anything else other than really looking for talent. If I can be a part of that I'm really down for it.''

Nicki says she has always been a fan of the programme - which is now entering its 12th season - and remembers when Jordin Sparks won the sixth series.

She said: ''I remember watching 'American Idol' in the first season and feeling inspired.

''I spoke to Jordin Sparks the other day and here she is starring in a movie ['Sparkle'] and I said to her, 'I remember watching you and picking up my phone.' ''

''I didn't vote for her because my brother liked the other guy, but I told her that, 'You know you're a part of history, kind of. Because I remember calling and seeing your face and being inspired and hearing your story.' ''
