Spot the difference between the two posh English girls who are both in the papers a lot these days, with this handy print-out-and-keep guide...

Harrys
Cressida Bonas: Currently dating Prince Harry, before that she dated Harry Wentworth-Stanley. Spent the weekend studiously seperated from Harry at the Missy Percy wedding to avoid photos, only to be snapped getting off the train with him in London and climbing into his Range, which sped off in the direction of Kensington Palace.
Cara Delevingne: When asked, “Are you dating Harry?’ Cara told Grazia magazine: "Which one? The prince? Or the other one? That was just a rumour, they both were. Both Harrys, just rumours. I know Harry [Styles], he's a good friend of mine, you know ... everyone's been linked to him."
Eyebrows
Cressida: Imagine eyebrows drawn on a balloon with a blackened cork. Reminiscent of Lego characters.
Cara: Bushy is the word of choice but this is an undersell. Cara has been taking eyebrow tips from Chewbacca.
Hair
Cressida: Tousled, shoulder-length, just-got-out-of-bed blonde mop.
Cara: Tousled, shoulder-length, just-got-out-of-bed blonde mop.

Cara: 20
Pedigree
Cressida: “Cressie” is the daughter of the original wild child, 1960s It Girl Lady Mary Gaye Curzon who had a cocktail named after her at Claridges, “The Blue Blood,” and posed naked covered in engine oil when posing naked covered in engine oil really was outrageous.
