With teenage superstar Justin Bieber's disastrous few days in London this month, a lot of people have been asking if this just-legal idol is poised for a spectacular fall from grace. His behaviour seems to indicate that one was due...

He has been photographed wandering the streets shirtless, wearing a gas mask, and with his pants pretty much hanging down on his thighs. He celebrated his "worst birthday" in the city, which reportedly saw him denied entry to a nightclub because he wanted to bring his 14-year-old pal Jaden Smith along.

He also - most notably - kept fans waiting almost two hours for him to take the stage at the O2 for Monday's show - reportedly because he had a late night the night before. He then posted a series of long, rambling tweets slamming his critics and saying he is only judged by "one power".

And to top it all off, he disappeared off stage for a few minutes during last night's show, with his manager telling his waiting fans that Bieber was feeling "light of breath". But, of course, the Biebs insisted on finishing the show (really, you can't buy PR like that) before he was admitted to hospital.

We decided to take a look back at other child superstars and their falls from grace... Just as a warning to the Biebs. And, because we're all about positivity, really - we pick the stars that seem to have made the transition gracefully.

Macaulay Culkin

Macaulay Culkin will forever be associated with the blockbuster comedy Home Alone, in which the actor appeared aged 10. He also starred in a few other films in the 1990s – including The Pagemaster, Richie Rich and My Girl, before retiring from acting age 14 and having his folks blocked from controlling his fortune. He returned to acting in 2000 after a six-year break, but his career never recovered. He was married for two years from 1998 to 2000, tying the knot when he was just 18, before dating Mila Kunis (Yes, Mila Kunis!) for eight years. He was also famously close friends with pop star Michael Jackson, and repeatedly defended him against allegations of child molestation. In 2004, he was arrested for possession of marijuana and controlled substances Alprazolam and Clonazepam – and after he was photographed in 2012, looking gaunt and appearing to vomit in the street, rumours emerged that the star was addicted to heroin and painkiller Oxycodone.

Lindsay Lohan

At age 11, a cutesy Lindsay Lohan wowed audiences with her big screen debut in 1998's The Parent Trap, before moving to films such as Freaky Friday and Herbie: Fully Loaded. By the time she was 18, Lohan had starred in the hit comedy Mean Girls and had a platinum-selling pop album, Speak. But her career and personal life took a dive from 2007, when she was arrested twice for driving under the influence, once with cocaine in her pocket. She was in and out of rehab a few times until 2010, and pledged to clean up her act – before being arrested for stealing a necklace from a jewellery store. She served her time under house arrest and temporarily seemed to have turned over a new leaf – completing all mandatory community service and therapy, and attempting to put her career back on track. Then she was involved in a car crash in July 2012 and has been accused of lying to police about it, and is facing the court on 18 March. She has - just this year - fired her long-suffering lawyer, was accused of ruining a designer dress and now owes massive amounts of taxes. This is not going well.

Haley Joel Osment

Although he had started acting aged four, Haley Joel Osment shot to fame aged 11 in 1999's The Sixth Sense, for which he was nominated for an Oscar. His career has stalled in recent years, with his last film being the voice of Mowgli in The Jungle Book 2 in 2003, and most of his work since being in video games. In 2006, the then-18-year-old was arrested after crashing and flipping his car while driving drunk and was found with marijuana on his person. He was sentenced to three years' probation and was ordered into rehab.

Amanda Bynes

Amanda Bynes started out with a promising career as the 13-year-old star of her own comedy The Amanda Show in 1999, before moving on to appear in What I Like About You and the starring role in What a Girl Wants. Her career has slowed in recent years – two of her last major roles were in 2007's Hairspray and a supporting role in 2010's Easy A. She has since faced a string of legal problems – being arrested in April 2012 for driving under the influence, and being involved in two separate hit-and-runs. Mercifully, she seems to have got her act together again since - or is at least flying under the radar.

Corey Haim

Once a teen idol, Corey Haim was probably best-known for his role in The Lost Boys, in which he appeared in with close pal Corey Feldman. Haim started taking drugs aged 15 and struggled with drug addiction for much of his adult life. In 1997, Haim filed for Chapter 11 bankruptcy protection, listing debts for medical expenses and over $200 000 in taxes. Haim failed in his attempts to get his career back on track, saying in 2007: "I wasn’t functional enough to work for anybody, even myself. I wasn’t working," Haim died of pneumonia in 2010, aged 38.

Gary Coleman

Diff'rent Strokes actor Gary Coleman spent his childhood in the popular sitcom, and at the height of his fame was earning $100 000 per episode – although he received only a quarter of it after paying his parents, advisers, lawyers and taxes. He later sued successfully for misappropriation of his funds and was awarded $1.3-million – which quickly disappeared and he was forced to file for bankruptcy. In 1998, he was working as a security guard at a mall when he punched a fan who allegedly mocked him for his failed career. In 2008, he ran over a man who had taken his photograph without permission, allegedly backing his truck in the man and hitting another vehicle. He was also involved in various domestic disputes. Coleman died in 2010, aged 42.

And some of the not-so-bad...

After a totally wild patch in her teens, Drew Barrymore managed to rein herself back in and has since become one of Hollywood's most successful stars. Ron Howard - who starred in The Andy Griffith Show aged just six - has become an immensely successful director. The trio of Harry Potter stars - Daniel Radcliffe, Emma Watson and Rupert Grint - have so far done well to avoid the child star trap, and have been working steadily and keeping out of trouble. Dakota Fanning - who starred in I Am Sam aged six - has been working hard at the transition from child star to teen actress, landing roles in The Twilight Saga and The Runaways. It's not all bad news, Biebs. Just keep it straight.
