It was a case of all eyes on her as she took to the stage to perform on Monday night.

And Katherine Jenkins certainly didn't disappoint in the sartorial stakes as she pulled out all the stops by opting for full-blown Hollywood glamour while attending the launch of Martell Cognac's Very Special Nights at London's exclusive Le Caprice eatery.

Injecting a pop of colour to her stylish ensemble, the Welsh songbird - who was performing at the event - wore a slick of bright red lipstick and fluttering false lashes, while completing her look with a delicate sequin-detail poppy.

The opera megastar wore her platinum blonde locks swept to the side to show off a pair of dazzling diamond drop earrings as she posed for photographs outside the event.

Proving that a classic look can sometimes be the best, Katherine's elegant dress highlighted her slim waist, while offering a generous glimpse of cleavage.

The star previously admitted she sticks to 'feminine, classy looks' when it comes to her sense of style, and is a fan of 'clean lines' and tailoring.

She said in an interview with Cosmopolitan magazine: 'I try and dress in things that suit my body shape because I'm quite curvy, I'm never going to have that stick thin figure, so I try and be feminine and classy but take inspiration from what is in fashion and adapt it to my figure.

'I really love cute little dresses, I'm far more of a dress girl than jeans. Day dresses are good because you can still feel girlie without feeling over-the-top.

'Things that are high-waisted suit me and I stick to outfits with cleans lines.

'I'm loving the shoulder pad thing right now! I got a McQueen dress the other day with shoulder pads and they make you look like you've got such a small waist - surely every girl loves that!
