Justin Bieber wanted to date Selena Gomez since he was 15.

A recording has emerged of the 'Baby' hitmaker admitting he had a crush on the former Disney star during an interview with Los Angeles radio host DJ Skee in 2009 - two years before they began to date.

According to TMZ.com after Justin, now 19, admitted his celebrity crush, he blushed, whispering ''Nobody heard that''.

He had his eye on the brunette beauty while she was still in a relationship with Nick Jonas, who she had been linked to since 2008, but in February 2011 Justin and Selena confirmed media speculation when they turned up at the Vanity Fair Oscar Party together.

The pair split in November last year after a two-year romance but have been seeing each other casually for the past several months and Selena has reportedly told friends she thinks he's ''The One''.

A source previously said: ''She's very stubborn when it comes to Justin. She's got this idea that he's 'The One' for her and that they'll live happily ever after.

''She's not ready to let go, and who knows, she could be right.''

Friends have previously insists the couple ''can't live with each other, they can't live without each other''.
