It's here! Yes, this week, TV viewers on both sides of the Atlantic get to see what Posh has been up to for the past six months - as Victoria Beckham: Coming to America finally hits our screens. But unless you've spent the first half of the year in a coma or living on another planet, you probably know far more than is absolutely necessary about Mrs Beckham's day-to-day life already.

Victoria Beckham: Coming to America airs on ITV1 at 9pm on Tuesday; repeated on ITV1 at 11pm on Wednesday night
