Singing YouTube star Madison Beer stuns in extremely daring see-through dress

YouTube singer Madison Beer, 20, has stunned onlookers with a racy outfit that features a cheeky side boob and a very high slit.

American YouTube star-turned-singing-sensation Madison Beer has turned heads in a very racy white dress.

The 20-year-old showed off a serious amount of flesh while attending the TrevorLive charity gala in Beverly Hills on Sunday night, giving onlookers a cheeky flash of sideboob.

But it was the Grecian-inspired gown’s racy thigh slit that caught everyone’s attention thanks to its super daring cut that appeared to go as high as her midriff.

As Madison posed in the unique dress — which was also made from a see-through material — her left leg was on full display.

In one snap, the star — who rose to fame after Justin Bieber discovered a YouTube video of her singing Etta James’ At Last in 2012 and signed her to his record label — looked as if she suffered a slight wardrobe malfunction as she posed on the event’s orange carpet. One thing’s for sure, she definitely wasn’t wearing any undies.

There were also several cut-outs across the chest, another element of risque to the outfit.

The singing superstar finished her risque look with a pair of white strappy heels and a dazzling smile as she supported the biannual event that celebrates the work of the The Trevor Project, which is working to end LGBTQ youth suicide.

Supermodel Heidi Klum also attended the star-studded event, rocking a sheer white dress with fringe detailing. On the carpet the 46-year-old twirled for the cameras, the strings from her gown swaying in a stunning photo moment.

Back in July, Beer was rumoured to be dating Brooklyn Beckham, though he has recently been linked to woman who bears a striking resemblance to his mum.

Last month, it emerged the 20-year-old was dating 27-year-old Phoebe Torrance, the daughter of former Ryder Cup golf hero Sam who has previously worked as a Posh Spice lookalike.
