Just ten days ago she revealed a short, tousled hairstyle, dyed a subtle auburn.

But now Rumer Willis has taken her look a step further with long, sleek, flame-coloured locks.

The 20-year-old daughter of The Sixth Sense actor Bruce Willis and his ex-wife Demi Moore, was snapped at LAX airport in Los Angeles with her new do. But it was unclear whether she owed her longer tresses to hair extensions or a wig.

Perhaps Rumer decided to develop her scarlet woman look after her auburn effort was well received.

The aspiring actress is well-known for her frequent fashion disasters. But when she revealed her red hair, stunning slender figure and new tattoo at the Teen Vogue Young Hollywood party on September 19, her often-savage critics were silenced.

But what will they make of this latest development?
