X Factor boyband JLS have dressed up as Britney Spears and filmed a spoof video of her number one 'Hit Me Baby One More Time'.

The group donned school uniforms and blonde pigtails ahead of the popstar's appearance on tonight's show.

Their eventful week also involved being dispatched to a speed dating event with 11 women by The Xtra Factor.

JLS are eager to progress into the semi-finals and were reportedly "shell-shocked" at finding themselves in the bottom two last week.

The X Factor airs at 7.35pm and 10.15pm tomorrow on ITV1.
