Hundreds of frenzied teenagers mobbed 16-year-old pop तारा, स्टार Justin Bieber and knocked down his mother as he arrived in New Zealand, stealing his hat as he was rushed through the airport to escape the fans.

The heartthrob Canadian singer tweeted his 2.1 million प्रशंसकों Wednesday to report: "Finally got to New Zealand last night. The airport was crazy. Not happy that someone चुरा लिया my hat and knocked down my mama. Come on people."

The star's mother, Pattie Mallette, tweeted that she was "OK" after being pushed over द्वारा rampaging प्रशंसकों at Auckland Airport late Tuesday. "Thanks for all ur support!! I'm ok thank you!!!," she wrote.

It was his mother's posting of वीडियो of Bieber गाना on YouTube that first caught the attention of the संगीत industry. His song "Baby" became a top-ten hit on iTunes earlier this year, and his popularity has grown to teen idol status.

Before arriving at the airport, the blond-haired singer had told प्रशंसकों that he wanted to sign autographs and have pictures taken. But police and security had to shut the opportunity down because प्रशंसकों were pushing.

The frenzy followed similar scenes in Sydney, Australia, earlier in the week, where police canceled a Bieber संगीत कार्यक्रम after surging crowds crushed some fans. The most serious injury was a fractured kneecap.

A similar situation occurred at a mall in Long Island, New York, in November. Bieber's free संगीत कार्यक्रम was canceled at the 11th घंटा when hundreds of प्रशंसकों stampeded after a reported sighting of the teen star.

In New Zealand, a mob of mainly teen girls screamed their welcome and swarmed toward Bieber at the airport. Escorted द्वारा security, police and minders, Bieber quickly left the airport out a side door.

A waiting black SUV whisked him away, leaving some प्रशंसकों sobbing with disappointment.

After Bieber's departure, teen Tory Shaffett कहा she was having trouble breathing.

"Oh my god, he was so amazing and beautiful. I can't believe I saw him," she told reporters.

Later Wednesday, Bieber wore an All Blacks rugby jersey and played drums at a संगीत lesson with a dozen teens at Strathallan High School for girls, before belting out half a dozen songs at an impromptu संगीत कार्यक्रम in front of 500 students.

He sang "One Time," "Never Let आप Go," "You Smile," "That Should Be Me, Baby" and "Favorite Girl" to his teenage girl audience.
