When it comes to dressing sexily, few manage it quite as well as Rihanna.

So when choosing an outfit to attend the singer's concert at Los Angeles' Staples Centre on Monday night, Rosie Huntington-Whiteley opted to get into the spirit of things by wearing a revealing outfit.

The 25-year-old model chose a pair skintight, bright pink leather trousers and a cropped top as she made an appearance at the event.

And British beauty Rosie probably made an extra effort to look her best as she had front row seats at the show, with pictures she posted on Instagram revealing her to be right in Rihanna's eye line.

Rosie looked effortlessly beautiful in her outfit, which shared all the hues of a candy cane.

As well as her hot pink trousers and baby pink top, Rosie lightened things up with a white blazer over the top.

Finishing her look off, Rosie wore a pair of nude Christian Louboutin Duvette shoes - stilettos with gold toe caps and further metallic detailing at the back and sides.

She kept accessories to a minimum, and carried a clutch bag big enough for essentials only, including her iPhone which she later used to snap some photos of the We Found Love singer in action.

In one, which she captioned 'so close', Rihanna can be seen just feet away shaking her long brown hair and singing in to a microphone.

Rihanna was excited for the show, and earlier tweeted to her fans about how much she was looking forward to the concert, which also featured rapper A$AP Rocky.

Rihanna had earlier found herself in a mini-spat with Kendall Jenner after she tweeted that she hoped Rihanna would play her favourite song.

'If Rihanna doesn't play Complicated tomorrow I'm gunna be very upset #FavSong' [sic] she tweeted.

The 17-year old model ignored Rihanna's mean tweet and came to the show to find out for herself if she would hear her favourite track.

She wore a pair of high-waisted jeans and a low cut, belly baring crossover crop top. 

On her feet she wore a pair of black boots, which came in handy as she left the concert and was besieged by fans - thankfully her bodyguard was there to keep her safe.
