Justin Bieber is here to explain the real reason why his 19th birthday was the "worst."

Justin and friends went to a nightclub in London for his birthday, and 14-year-old Jaden Smith — son of Will Smith and Jada Pinkett Smith — reportedly showed up at the club, causing underage problems and leading to Justin's "worst birthday" tweet. Well, not so fast.

Justin took to Instagram to correct the rumors:

"The funny moment when people believe I brought underage people to a club.. U think Will 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."

It was just an impassioned tweet in the moment that got blown out of proportion — and somehow JB’s “Never Say Never” pal got involved. So maybe it wasn’t really his worst birthday ever, but it’s probably one of his worst post-birthdays ever!
