The Saturdays are doing all they can to reach that number one spot with new single ‘Missing You’. Bandmember Rochelle Wiseman takes it one step further and strips to her undies.

Rochelle, 21, chose see-through knickers and flowery bra for the photo that hopefully will seduce people into buying The Saturdays single.

The girls are hoping to knock Ne-Yo’s Beautiful Monster off the top of the charts tomorrow.

And they hope to keep Flo Rida’s Club Can’t Handle Me at bay.
