She was shooting for her new clothing line Ibiza x Demi Rose

She proved to be her own best advert as she modelled a blue two-piece from her new clothing line.

She was at another sizzling pH๏τo shoot in IbizaDemi stunned in the bralet and thong, which showed off her tiny waist and most of her bum to all.

She styled her hair into loose waves, and teamed the swimwear with glamorous studded heels as she posed Sєxily by the pool.

The Instagram model was promoting her new swimwear line, Ibiza x Demi Rose, with ISAWITFIRST.COM at the shoot.

Demi designed the range to suit girls with “hourglᴀss figures” like hers, after years of struggling to find clothes that fit properly.

The Birmingham-born star has spent much of the summer shooting in Ibiza, as well as working on her new Kardashian-style app.

The app keeps her fans updated with her latest business ventures and pH๏τo shoots, much like the one launched by Kylie Jenner three years ago.

Demi already has a huge Instagram following, with 7.5 million people signed up to her account thanks to her regular Sєxy snaps.

Despite her modelling success however, she dreams of cracking America and carving a career in acting.

Speaking exclusively to The Sun Online, Demi said: “I’ve been taking acting classes once a week and they are helping to build my confidence.

“The plan is to move to Los Angeles as soon as I can get a working visa.

“I can’t be sure I am going to make it but I want to try my best.”
