Jaden Smith says there’s no way he ruined Justin Bieber’s 19th birthday -- because he wasn’t even there!

According to multiple reports, the 14-year-old son of Will Smith and Jada Pinkett Smith was the reason Bieber and his pals got booted from a London nightclub after the pop star attempted to sneak him in despite his underage status.

Bieber went on to tweet that his evening was the “worst birthday ever.”

“The funny thing is, I could have gone, and I didn’t feel like it -- that’s not my vibe,” Jaden claims in the May 2013 issue of Nylon. “I knew something was going to happen…even though I didn’t do anything.”

Jaden says that instead of attending his friend’s wild birthday celebration, he was at a Kanye West concert in London. Photos posted on Instagram by his rumored girlfriend support his claim; however, the concert ended late Friday night and Bieber and his pals didn’t even arrive to the Cirque Du Soir nightclub until around 1:40 am on Saturday, according to the reports.
