The former Girls Aloud singer took the opportunity to showcase her new 'do at the Best of British Talent Party in London last night (4 February).
Sarah is well known for her blonde locks and was previously rocking a longer golden style with a side fringe.
Clearly craving an image overhaul, she made the brave choice of lopping off her tresses so they just about graze her jawline.
The starlet also opted for a much paler platinum hue, plus a long lash-skimming fringe (so long in fact, we're surprised she could see!)
Sarah complemented her new bonce with black liner and matte red lips while wearing monochrome co-ords.
Bobs have been huge for a while now, but recently even more celebs have been jumping on the short-haired bandwagon.
Hollywood babe Jessica Alba cut her tousled waves into a graduated style last week, while TOWIE's Jessica Wright swapped her tumbling mane for a shorter 'do too.
We can't say we blame them, imagine the blow-drying time they'll save...
