That pretty little blond gal you saw before is Nathan Sykes' little sister, Jessica Sykes! The youngest member of the Wanted is such an awesome big brother to Jess, who is three years younger than her famous brother. The picture above is of Jess before her prom, and of course Nathan had to be there to see his sister off.

They are in constant interaction over Twitter -- we love Nathan even more after learning about what a great brother he is -- and she supports the Wanted through social networking as well. And looks aren't the only thing these two have in common -- like Nathan, Jess is also a talented singer. You can check out the video below of her singing Etta James' classic 'At Last.'
