Love Story singer Swift and Baby hitmaker Bieber were selected for consistently showing courtesy to their fans while veteran Abdul was picked for her always-encouraging words of wisdom to aspiring performers as a judge on America’s musical talent show The X Factor.

British royal Catherine, the Duchess of Cambridge topped the list for exemplifying poise and dignity in the spotlight, while Harry Potter beauty Emma Watson, athlete Aaron Rogers and child star Jackie Evancho were also applauded.

On the other hand, reality star Kim Kardashian received the shameful crown of Most Ill-Mannered Person of 2011, for "making a private matter public and disrespecting the institution of marriage".

The reality star had split from basketball player husband Kris Humphries just 72 days after their high-profile wedding.
