Sir Elton John has warned Miley Cyrus is on the verge of a major breakdown. The music legend is convinced he is able to spot the warning signs before troubled stars crack, insisting he correctly predicted the downfall of late legend Michael Jackson, and tried to help Whitney Houston before her death last year (12). He has now issued a stark warning about former child star Cyrus, admitting he fears the 20 year old's headline-grabbing antics over the last few weeks after signs of trouble brewing. He tells TheAustralian.com.au, "I look at Miley Cyrus and I see a meltdown waiting to happen. And she's so young! But she's got two records in the top 20, so who is going to stop her?... Maybe it's a British thing, but I can spot a car crash before it happens. I was in my dressing room in Las Vegas when they announced that Michael Jackson was playing 50 dates at the O2. I turned to my agent and said: 'He won't do a single one of those.' I could tell you he was going to die..." The Rocket Man star also cites troubled singer/songwriter Ryan Adams as a prime example, insisting he tried to help him battle his alcohol and drug problems, but the rocker didn't want to listen. He adds, "Sometimes you try and reach out to someone and tell them they're going to have a car crash, like I did with Ryan Adams, Ryan didn't listen to me. He had the car crash, he recovered, and now he's back and on great form." Adams subsequently apologised to Sir Elton, who battled his own drug problems in the past, for refusing his offer to help him get sober.
