Demi Lovato. Picture: Twitter

Demi Lovato has laughed off her photo hack – insisting she doesn't care if the world sees a cleavage pic of her.

The 'Really Don't Care' hitmaker took to Twitter on Tuesday, March 21, to address reports that private photos of her naked have been accessed and leaked.

While she has seemingly confirmed the hack took place, the 'Heart Attack' singer insists the pics are far from racy.

Taking to the micro-blogging site, she wrote: "I love how everyone's freaking out about one picture. It's not nude and it's just cleavage (sic)"

The 24-year-old pop beauty – who is dating MMA fighter Guilherme 'Bomba' Vasconcelos – also joked about how there are already images of her showing off her ample assets widely available to the public including a previous shoot for Vanity Fair magazine.

She added in another tweet:

According to various reports, Demi was seen posing on a bed in an unzipped hooded top in the shot.

However, it's not the first time the brunette beauty has been caught up in a photo hack.

In 2013, pictures surfaced of her in bed with her ex-boyfriend Wilmer Valderrama, which were reportedly meant to only be shared with her partner.

At the time, the hacker told RadarOnline: "These are Demi. The collection I have show some nude, including face, some including parts of the body Demi is known for – tattoos, butt, chin.

"Then, I have pictures of her getting rowdy ... I can guarantee you these photos are legitimately of Demi."

Demi joins a long list of celebrities who have been targeted by online bullies including most recently 'Beauty and the Beast' star Emma Watson, Mischa Barton and Amanda Seyfried.
