We wouldn't look twice at Cameron Diaz's sister in the street

Having a celebrity brother or sister Cameron Diaz or like Julia Roberts must have its perks. Free tickets to glamourous movie premieres or perhaps even erm, a front row seat at the Academy Awards and a chance to make it into an epic selfie (we’re looking at you, Peter Nyong’o)!

But it can also have its drawbacks – constantly being compared to your famous relative could be tiring. Or it might mean having looks thrown at you that seem to ask why your name isn’t in lights too.

Or why having a world-famous brother doesn’t even get you past judges’ houses on The X Factor. Ahem, Lizzy Pattison.

In our gallery above, it would be next to impossible to recognise these celebrities’ brother or sister if they weren’t standing right next to their well-known sibling. 

Be honest, would you blink an eye at Sami Hayek if he wasn’t standing next to his sister Salma? Or would you be ready, smartphone in hand if Gwyneth Paltrow‘s brother Jake walked past them in the street?

Or if your Tinder date ended up being a chap called Dan Swank, would it cross your mind that he might be related to two-time Academy Award-winner Hilary Swank?

And if Debbie Holden was sitting next to you on the tube, there would be a slim chance of knowing she was related to Britain’s Got Talent judge Amanda Holden.

Sarah Jessica Parker might be a Hollywood legend but her brother Pippin – besides being called Pippin – looks like the accountant who does your taxes.

And Lex Meester doesn’t seem to have inherited any of his sister Leighton‘s fashion sense. Lex looks like he’s been taking style cues from Facebook founder Mark Zuckerberg.

But perhaps most shocking of all is Wayne Rooney‘s younger brother Graeme – Coleen must be thanking the stars she fell for the right Rooney!
