The bold number, which boasted several studded accents, a structured bodice and a plunging neckline, appropriately covered her ample assets and toned curves.

With her dark locks coiffed into a stylish quiff, a bold red lip, soft lilac eyewear and lashings of black mascara gave the look the perfect edge.

St. Vincent, real name Anne Erin Clark, happily got the crowds to their feet as she sang through some of her songs while writhing across the stage.

Last weekend, 22-year-old Cara was seen showing her support as she watched the American star dazzle crowds at Osheaga festival in Montreal, Canada.

In a failed attempt to go incognito, the British beauty was pictured showcasing an eye-catching bright pink wig, which was styled further with a purple and black patterned bandana.

But Cara wasn't the only one to sport a wig on the day, as her pal and Suicide Squad co-star Margot Robbie also covered her blonde locks in a black wig for the occasion.

Meanwhile, it appears as if things are still going well with St. Vincent and the aspiring actress.

Last month, it was rumoured the loved-up couple - who have been dating for eight months - had called time on their relationship.

However, a source close to the stars confirmed at the time they were still 'very much together'.

'They're still together and very happy. Everyone seems to want them to split up - but the fact is Annie is in Europe on tour and Cara is working in the States,' the insider said, before adding, ‘They couldn't be happier and the latest reports are yet again just ridiculous.'

The US musician is thought to have been dating Cara since December 2014, with the 22-year-old model confirming the relationship earlier this year, just days after the couple made their public debut at a fashion party in Los Angeles.
