"American Idol" and "The Voice" are duking it out on prime-time TV right now, but don't forget that there is yet another talent show on the way: "The X-Factor."

Now, former Idol judge Paula Abdul has signed on as the fourth and final judge of 'The X Factor,' according to the Hollywood Reporter.

Sources say that negotiations went down to the wire, due in part to her deal with CBS to appear on the dance-competition series 'Live to Dance.'

By joining 'The X Factor,' Abdul will be reunited with her 'American Idol' partner, Simon Cowell, along with judges Cheryl Cole and Antonio "L.A." Reid.

Meanwhile, PopCrush is reporting that Pussycat Dolls singer Nicole Scherzinger will co-host 'The X Factor' with British TV personality Steve Jones.

So, "Idol" is almost done, "The Voice" is just getting started, and by the time it's wrapping up we'll have  "X-Factor", I wonder how long all these shows can go on before Americans just don't care at all. I think one will have to jump to the forefront and become THE show to watch or all three will end up fizzling out.
