DEMI Lovato oozed body confidence in her racy Halloween costume last night.

The singer showed off her curves in a sexy policewoman outfit which included a black long-sleeved PVC style bodysuit that was unzipped to highlight her cleavage.

The 25-year-old completed the look with fishnet tights, black boots and a police hat and was happy to pull a series of sexy poses for snaps she shared on Instagram.

She captioned one image: “Protect and serve 👮🏻‍♀️😜 Happy Halloween 🎃”

While she wrote under another: “Watchu gon do when they come for you?”

Demi’s racy display comes just weeks after she opened up about how she used to smuggle cocaine onto planes and nearly died from an overdose of prescription pills.

The singer and actress spoke candidly about her struggle against addiction in her new documentary Simply Complicated.

After seeking help back in 2010 for alcohol and drugs dependency, the star relapsed two years later.

She said: “I wasn’t working my programme, I wasn’t ready to get sober.

“I was sneaking [cocaine] on planes. I was sneaking it in bathrooms, sneaking it throughout the night.

“I went on a bender of like, two months where I was using daily.”

She recalled: “There was one night when I used a bunch of coke and I popped a few [prescription] Xanax bars, and I began to choke a little bit.

“My heart started racing, and I thought to myself, ‘Oh my God, I might be overdosing right now.’

But it didn’t stop Demi and she ended up being placed on psychiatric hold after she downed half a bottle of pills.

She recalled: “I didn’t feel anything. I didn’t feel guilty, I didn’t feel embarrassed,” and admits she went on to fake drug tests using “other people’s pee.”

The star also discussed the infamous incident where she punched her backup dancer back in 2010 which prompted her to seek treatment in rehab.

She admits: “In remember thinking ‘I’m gonna beat this b*** up.”

Nowadays, Demi’s struggle is far from over and she admits she last year suffered a relapse with her eating disorder after her split with actor Wilmer Valderrama.

She said: “When I feel lonely, my heart feels hungry and then I end up bingeing. And I don’t know how to figure out how to be alone.”
