“The funny moment when people believe I brought underage people to a club,” he shared on Instagram. “U think Will [Smith] is letting his 14 year old in a club, I don’t think so.. 2nd I love how the club wanted to give the press another reason to why we didn’t stay at their weak ass club so they wouldn’t look bad for me walking in and right back out..i said m “worst bday” but that was due to dummies pushing over my fans and being overly aggressive. Btw it wasn’t the worst bday cuz all my friends from back home flew in I was just mad in the moment.”
