It's been a confusing couple of days.

First we discover that we are, in fact, a completely different star sign to what we have always believed we were. Thanks, NASA. Hello, existential crisis.

Then, Cara Delevingne throws a body art curveball.

The model-turned-actress stepped out at Burberry's 'September' show sporting what first appeared to be a bold new tattoo - a black line running from her neck to her belly button, straight down the centre of her chest, perfectly framed by the plunging neckline of her dress.

Delevingne is the proud owner of numerous tattoos, including one given to her by Suicide Squad co-star Margot Robbie, and her most recent addition, an elephant on her inner arm.

On closer assessment, it seems her latest is a temporary feature, but what does it mean?

Frankly, we have no idea but could this be the start of a new trend? We wouldn't doubt it. It reminds of us Lily Collins' make-up look at this year's Met Gala...
