Demi Lovato proudly bares toned abs in Instagram selfie: 'I'm feeling myself right now'

Demi Lovato is all about body confidence right now. The Heart Attack singer has stuck to an intense workout regime for several months and the results are impressive. In an Instagram selfie, Lovato bares her toned abs while proudly boasting of her achievement.

During her year-long break from music, Lovato, 24, has made it her mission to get into shape ahead of her anticipated comeback. After taking up a personal trainer, promoting detox smoothies and even teaming up with sportswear brand Fabletics, Lovato has finally transformed her body.

In the selfie, posted on 2 August, Lovato is seen wearing a cropped sports bra while pulling down her tracksuit bottoms to reveal her taut and toned stomach.

Alongside the photo, Lovato wrote an inspiring message to her 59.8 million followers, which read: "I rarely post pics with my belly button showing because I'm normally insecure about showing my full stomach but I've been working really hard and thanks to @d.leith and his yummy food with @lockhartandleith I've been seeing progress so I thought I'd post this cause I'm feeling myself right now!!"

Praising her new physique, one fan commented beside the Instagram photo: "You look amazing! Strong, healthy and confident. You go girl."

While another enthused: "You have nothing to be insecure about, you have always been beautiful!"

Offering a positive suggestion, another follower said: "I think you should make a book about your story and struggles with mental health. I think it could help many people and inspire them."

Lovato's fit and healthy figure is even more empowering as the pop star has battled eating disorders, such as bulimia, in the past. Speaking to American Way magazine in 2016, Lovato said of her personal struggles: "Even though I was two or three years old. Being around somebody who was 80 pounds and had an active eating disorder... it's hard not to grow up like that. Hopefully my kids won't have it [bulimia], but it's kind of like addiction. It's hereditary."

With her new lease of life, Lovato has now revealed to radio personality Elvis Duran that she does not want to be defined by her bipolar disorder. The singer explained: "I think when people refer to me as being bipolar, it's something that's true – I am bipolar – but I don't like people to use it as a label. It's something that I have, it's not who I am."

"I think it's very important that people raise the importance of mental health because it's something that's so taboo to talk about. The more people know about it, the more people are going to be able to find solutions to what they're going through."
