Miley Cyrus and Chris Brown voted worst celebrity role models for kids

Miley Cyrus and Chris Brown have been named and shamed as the worst celebrity role models for kids, according to a new survey.

Former Hannah Montana star Cyrus, who got engaged at 19, topped the female version of the CouponCodes4u.com poll, earning 68 per cent of parents' votes after moving away from her squeaky-clean image, narrowly edging out embattled Lindsay Lohan, who is currently in court-ordered rehab, by three per cent.

Reality TV star and new mom Kim Kardashian came in third place, while Amanda Bynes and former Teen Mom star Farrah Abraham rounded out the top five.

Meanwhile, Brown was unveiled as mom and dads' most unpopular male pick, taking 71 per cent of the vote following his infamous 2009 assault of then-girlfriend Rihanna.

Kardashian's boyfriend, rapper Kanye West, was second with 67 per cent and teen superstar Justin Bieber took third place, thanks to his recent hard partying and allegations of reckless driving. Lil Wayne and Charlie Sheen complete the men's countdown at four and five, respectively.
