POP phenomenon Justin Bieber delighted a Sydney fan at Palm Beach today in a chance meeting when he sang to her for her birthday - and Tweeted about it.

At a well covered-up visit to Palm Beach in Sydney's North, where hit soap Home and Away is filmed, Bieber Tweeted that he had enjoyed meeting the fan and hoped she had a great birthday.
"Happy b'day to Prudence who we met today by the beach. glad we got to sing for u."
The usual throng of media was not present at the beach, instead just a handful of media were there, indicating Bieber's security is effective.
Later that night, the Baby singer ate at Bondi Beach and went home to write some more songs.
Earlier on Saturday, Bieber and Slash arrived in Sydney after becoming good buddies while travelling on the same flight from Tokyo to Sydney and already, 16-year-old Bieber has invited himself to a meal with the former Guns N Roses superstar.
"Want to have dinner with Slash tonight in Sydney, Australia,'' Bieber said on Twitter.
The teen idol also spoke favourably of his surroundings.
"Just arrived and I like Australia,'' he tweeted. "I like the weather, the accents, the girls, the water, the excitement, the girls and - the girls.''
Bieber will be in Sydney until Tuesday promoting his album, "My Worlds" while Slash is in Australia to launch a music television channel, MTV Classic, in Melbourne on Wednesday.
For those not in the loop, Bieber looks 12, and sounds younger.
But legions of tween and teen girls think the Canadian pop phenomenon is bigger than the Beatles, even if most music fans over the age of 15 have never heard of him.
Bieber fever has swept the globe - thanks to his mother Pattie Mallette posting online videos of her son doing covers of hits from Usher, Justin Timberlake and Stevie Wonder.
When an astute record industry insider spotted the raw home-made clips, he arranged for the Ontario teen to meet his now mentor Usher and, within months, Bieber was signed to a lucrative recording deal.
He has been propelled to the top of the charts worldwide by an obsessed fan base who constantly request radio stations play his singles including Baby and One More Time.
The all-dancing, all-singing, drum, guitar and trumpet player has been propelled to the top of the charts the old-fashioned way.
Just like The Beatles, Bieber releases single after single to satisfy his fans. People like Sarah Adamson, a 15-year-old Parramatta girl who is planning to camp out with her friends and a parent to score a front-row spot for Bieber's only Sydney performance - at the Overseas Passenger Terminal on Monday morning.
"We checked him out on YouTube and became his biggest fans right away. He has the best voice of anyone in the world. And he's very hot," she gushed.
"I've got all of his songs and his photos on my phone and a poster of him in my bedroom. I just want to be able to run up and give him a big hug."
And so do about 5000 other besotted girls, some from as far afield as Perth, Darwin and Hobart, who will be descending on Circular Quay, prepared to scream their lungs out.
A spokeswoman for Sunrise, who will broadcast Bieber's three-song performance and chat, said they have organised extra security, police and St John Ambulance - in case anyone faints courtesy of Biebermania.
