Demi Lovato warns pal Miley Cyrus of the dangers of drugs after star 'confirms MDMA reference in her hit song We Can't Stop'

She recently admitted that she references the party drug MDMA in her hit song, We Can't Stop.
And with her past antics, which also includes reported marijuana use, Miley Cyrus is now seemingly marketing herself as a party girl.
But her actions have left many worrying, including gal pal and former Hannah Montana co-star Demi Lovato, who herself sought help for substance use, emotional issues and cutting in 2011.

Pals: Demi Lovato has cautioned her old pal Miley Cyrus (pictured together in April 2009) about the dangers of partying and doing drugs

In a new interview with MTV News, Demi says that she has cautioned her friend on the subject of partying.

'She knows how I feel about the whole partying thing…' Demi said. 'And I’m always like, "Just be careful." And she’s like, "Dude, I’m chilling. It’s fine."'

For now, Demi says that Miley's actions have yet to cause her any real reason for major concern.

'I care for (her) so much (that) I’m so protective, but she’s good,' Demi explained in the interview. 'She’s got a good head on her shoulders.'

Demi has said in the past that she refuses to surround herself with people who indulge in risky behaviour, and it seems that Miley will continue to stay in her life.

'I surround myself with people that are beneficial in my recovery and my recovery is still a daily battle and I definitely hang out with people that support me in making the right decisions,' she has once said.

'I’m a happier and healthier person today because of the choices I’ve made.'

Demi, whose hit song Heart Attack is up against We Can't Stop in the Best Female Video category at the upcoming MTV VMAs, says she actually likes Miley's party anthem.

'I think it's great,' Demi said about the track.

'I think it's a good song... It's a song a lot of people have fun to and if people are enjoying it, then great.'

Produced by Mike WiLL Made-It and co-written by Miley, Mike WiLL and Rock City, Miley's new song We Can't Stop features risque lyrics that appear to refer to illegal drugs.

'La-da-di-da-di, we like to party/Dancing with Molly,' is one of the lyrics.

Molly is widely regarded as a slang term for a pure form of the party drug ecstasy.

Provocative: Miley has increasingly become known for her provocative dance moves, including her famous 'Twerking'

In a recent interview with the Daily Mail, Miley seemingly confirmed that she was in fact singing about the drug.

'It depends who's doing what. If you're aged ten [the lyric is] Miley, if you know what I'm talking about then you know,' she told the Daily Mail.

'I just wanted it to be played on the radio and they've already had to edit it so much.

'I don't think people have a hard time understanding that I've grown up. You can Google me and you know what I'm up to -- you know what that lyric is saying.'

Miley, who has well and truly shed her good-girl image, also revealed that the video for We Can't Stop was in fact more explicit than the version played in the UK.

'They’ve edited the video here in the UK. They put a big X over my mouth ’cos I was going like ‘this’ (she makes a gesture for oral sex).'

She continued: 'No gyrating, no ***********, there was a lot less. They took out literally everything. I thought the video wasn’t bad, then MTV in the UK sent, like, 18 notes asking for changes.'

She admitted she wasn’t concerned about alienating her younger fans.

‘I wasn’t really worried about it because I feel that time was something that I had to do what everyone has to do – work at something that you don’t necessarily love to get to be able to do what you do love,’ she said.

Continuing, she added: ‘I would say everyone has to start from the bottom, to get where they want to go and work on things they don’t really care about doing.

‘So I had to do that for five years. I had to work on something that wasn’t really a passion for me just because I wanted to be able to get here, so when I was older I’d be able to just do what I want and not have to work for money.'

While the video has raised eyebrows, Miley insisted that it isn’t really too provocative and when we asked what she would say to those who think it is, she quickly responded making a reference to the recent Trayvon Martin trial in the US, which saw George Zimmerman found not guilty of murdering the black teenager.

She replied: ‘Then I’ll give you an edit. I just think the world is so lame because you can shoot people in a movie and you can let people like Zimmerman off on trial but you can’t have someone going like this ( she stimulates oral sex gesture), that is so dumb to me.

Clearly passionate about the issue, she continued: ‘The world is such a ***ked up place the last thing people need to worry about is my cute little video for We Can’t Stop, you know what I mean?

'People need to also remember that Britney when she did Slave or anything it was just a different time so it was less real because Can’t Stop I wanted it to be kind of gritty, like everything is about Instagram, about things going viral and I wanted to celebrate that.

‘But Britney or Madonna never played it safe, none of the best pop artists ever did.  I feel like I live in a different world, I live in LA, I see everything.'
