Kate Garraway’s Life Stories ITV, 9pm

Charlotte Church (below) was initially billed as appearing last week, but a change in the running order means she's now Garraway's final guest of the series. The interview should be worth the wait, though, as the singer discusses rocketing to fame at the age of 12 and the pressures of growing up in the public eye. She also speaks candidly about her turbulent love life.
