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 dailystar.co.uk.

“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.
