The Kiss Kiss hitmaker turned 22 and teen idol Bieber was keen to speak to Brown on his special day, following their performance together in Sydney last week (28Apr11).
But Brown programmed his new number into Bieber's cell phone incorrectly - leaving the Baby hitmaker blushing after an awkward conversation with a stranger.
In a series of posts on his Twitter.com page, Bieber writes, "Chris Brown happy birthday man... call me cuz (because) u programed (sic) yr (your) new number wrong in my phone. I was calling this old guy who didn't believe he was talking to me."
