Today is music artiste Ice Prince's 30th birthday and his friend, OAP Toolz took to IG to wish him a Happy Birthday!. She wrote:
"Happy birthday lil bro!! God blessings always! @iceprincezamani" This appears to have disturbed a random man, who questioned her 'audacity' for calling him - 'lil bro'. Lol..
