Mariah Carey dazzles in two very sexy gowns at the World Music Awards

She's long been known as a diva.

And on Tuesday night, Mariah Carey proved that's still the case as she arrived four hours late to open the show at the 2014 World Music Awards, held at Monte Carlo's Le Sporting Club in Monaco.

The 44-year-old was all set to launch her new album, Me. I Am Mariah... The Elusive Chanteuse, prior to the awards show, but when it was pushed back by several hours, the proceedings were thrown into chaos.

Worth the wait! Mariah Carey dazzled the audience at the 2014 World Music Awards at Monte Carlo's Le Sporting Club in Monaco on Tuesday night despite being four hours late after her album launch was delayed

'Mariah was meant to be at the Sporting Club at 5.30pm but her album launch was put back to 9.30pm,' The Mirror reports a senior producer as explaining. 'The whole event has been delayed.
It's not great.'

However, it seems not everyone was aware of the cause of the delay, with a World Music Awards spokesman not mincing words as he said rather harshly: 'We don't know why Mariah is late, she's
just being Mariah.'

When she did finally arrive, the 44-year-old was in fine form as she took to the stage to belt out
a tune.

The star looked sensational in a long-sleeved floor-length sparkly black gown that featured sexy sheer panels all over - her modesty only protected by skimpy black underwear - and a plunging neckline that exposed plenty of cleavage.

'The whole event has been delayed. It's not great': While the show's producers scrambled to rearrange the schedule after learning that their opening act was running late, they were rewarded when she eventually took to the stage for a pitch-perfect performance

Picture-perfect: The 44-year-old looked absolutely stunning with her face full of heavy, perfectly-applied make-up featuring a golden base, dark, smoky eyes and glossy nude lips, framed by her blonde tresses, which were styled in soft waves, and huge dangly diamond earrings

She was wearing her now-signature black fingerless glove on her right arm, while she accessorised with a glitzy diamond bracelet in the shape of a snake, dangly earrings and a butterfly ring.

Her long golden tresses were worn in soft waves and her face was beautifully made up in complementary golden tones, with dark, smoky eyes and nude glossy lips.

As well as performing during the star-studded ceremony - which also saw the likes of Miley Cyrus, Leona Lewis, Ricky Martin and Jason Derulo in attendance - the original diva was also the lucky recipient of two awards.

She was awarded the Pop Icon and Best-Selling Solo Artist Of All-Time gongs and took to the podium to make a gushing speech dressed in her second outfit of the evening.

Confetti shower! Large round gold confetti fell down from the ceiling as her performance concluded, with one piece getting rather unfortunately lodged between her breasts in her plunging gown

Daring to bare! The mom-of-two wowed in her sparkly black long-sleeved floor-length gown, which featured sexy sheer panels all over, her modesty protected by skimpy black underwear

She's still got it! The songstress's impressive vocal range was in fine form during her rendition

The number featured silver diamantés in all the right places to protect her modesty, with a sheer long-sleeved underlay that fell to the floor, which was also scattered with the sparkling jewels.

Posting several photos with her awards backstage in her dressing room as she was joined by her three-year-old twins, Moroccan and Monroe, the proud mom gushed that no award could measure
up to her precious babies.

'The best awards I've ever received: Roc & Roe!! Thank you Melissa & all at the World Music Awards in Monte Carlo #L4L,' she wrote to accompany the sweet black and white shot of her kids playing with the shiny statuettes.

In another show of her divaliciousness, Mariah even arrived with her own lighting guy to ensure she looked her absolute best at all times.

'She likes to have her lighting man wherever she goes to make sure the lighting is right. That's really important to her,' a source tells The Mirror.

Wardrobe change! Mariah switched into an equally revealing sheer gown that was covered in a smattering of silver diamantés in all the right places as she returned to the stage to accept two awards during proceedings

Quite the accomplishment: The singer gave a gushing speech as she was presented with the awards for Pop Icon and Best-Selling Solo Artist Of All-Time on the same day she released her first album in four years, Me. I Am Mariah... The Elusive Chanteuse
