O'Leary tipped to host US 'X Factor'

Dermot O'Leary is expected to host the US version of 'The X Factor'.

The 36-year-old presenter – who currently fronts the reality singing show on ITV1 in the UK – impressed producers at a recent meeting in Los Angeles so much, it’s now likely he'll go to the US with Simon Cowell when he launches the show overseas in 2011.
