The stunning floor length red gown Ennis donned clung to her curves and showed off her perfect figure and a pert derriere which is considered almost synonymous with Middleton. After this appearance, there will be more than one person associated with the perfect derriere most women crave for and most men drool over.

The sleeveless V-neck dress clinched at the waist with a black belt showed off her nicely tanned decolletage, her perfectly toned and athletic arms and her svelte figure. With her hair left loose and a tinge of eye shadow, blush and lip color, Ennis accessorized her attire with a black clutch, a classic watch and a simple chic necklace. Posing for photographs on the red carpet with fiancé Andy Hill, the 26-year-old made sure all eyes were on her.

Ennis won an award for standing second in BBC's Sports Personality of the Year and received the award from Kate Middleton. But it was not only her butt that caused frenzy. As much as the fans talked about how she had overtaken Pippa, some were even miffed with the athlete's ignorance when the Duchess congratulated Ennis.

Ennis seemed to be unaware of Kate Middleton's extended hand. Though it looked like a genuine mistake as she was holding the trophy and didn't notice the Duchess' hand, fans are not really happy with the ignorance.

The event was Middleton's first public appearance after being discharged from a three-day stay at the King Edward VII due to severe morning sickness.
