Demi Lovato looks absolutely amazing – and she’s not afraid to admit it.

The singer, who recently hit out at Pink after she dissed the MTV VMAs, headed to Radio 1 studios in London on Wednesday.

Demi didn’t come dressed for the radio – far from it – and instead rocked up wearing a strapless black jumpsuit.

The stylish number clung to the brunette’s midsection, in the process showing off her super trim waist.

She teamed the get-up with a floral-print blazer before rounding off her look with a pair of eye-catching turquoise heels.

During the outing the singer performed in the Live Lounge, singing her new track Cool For The Summer as well as a cover of Hozier’s Take Me To Church.

Afterwards Demi, who has battled bulimia in the past, confidently opened up about her fabulous appearance with host Clara Amfo.

She said: “I have worked on myself and I look hot, so I’m going to work it.”

“I’m going to show the world that you can go from having an eating disorder and hating your body to wearing underwear on the cover of a magazine and love it. You know, it’s possible.”

Last month Demi, who is dating Wilmer Valderrama, really flaunted the goods when she stripped off to a bikini.

The former Disney star looked sensational in the two-piece and made sure to send a positive message to her fans before positing it on Instagram.

She wrote: “Learn to lurrrrrvveee yerrrrr currrrrvveees… I actually used to hate them… But then a special someone helped me learn how to love them… And he sure loves them…. #squats.”
