Usher`s musical gift to Beckham`s son

London: Soccer player David Beckham`s son Brooklyn received a memorable surprise on his 13th birthday -- a musical wish by his favourite singer Usher.

Brooklyn`s celebrity parents David and Victoria decided to call in a favour from their friend Usher, asking him to serenade their eldest son down the phone, reports

"Brooklyn is naturally quite shy and isn`t one for courting attention, even on his birthday. As he was unwrapping a new Arsenal football kit, David casually walked in telling him there was someone on the phone who wanted to wish him happy birthday," said a source.

"When he picked up the phone, Usher sang Happy Birthday. Brooklyn is crazy about Usher and has met him a few times. He went bright red and started to get really shy. He told his dad afterwards that it was `the best birthday present ever`," the source added.
