OTRC: Justin Bieber Tweets about his 'worst birthday,' reportedly ends night with club confrontation

Justin Bieber appears in a photo from the Billboard Music Awards on May 20, 2012.

Justin Bieber's 19th birthday on Friday, March 1, wasn't a good one, according to the singer himself.

The teen heartthrob let his fans know about his unsatisfying birthday experience with a simple Tweet on March 1 first that said, "Worst birthday."

Bieber didn't elaborate what exactly happened on any of his social media profiles beyond that Tweet.

According to E! News, Bieber's birthday celebration was a circus-themed party at the Cirque du Soir in London. However, the night ended abruptly with a confrontation between the singer's entourage and the club's security. The incident led to the birthday group leaving the club and the singer heading right back to his hotel.

Fans on Twitter are apparently hoping to cheer Bieber up because the term "#OperationMakeBieberSmile" was trending on the social network at the time of this writing.

The previous night Bieber was spotted shirtless after his concert in Birmingham, just outside of London, getting ready to celebrate his early birthday. At the time, Bieber was seen wearing bright blue leather pants with white briefs underneath.

His manager, Scooter Braun, explained why the singer was shirtless to Access Hollywood on Friday, March 1.

"He was coming right off the stage -- the show was done," Braun, told the entertainment news outlet. "He was coming off the stage and going to the hotel and he was literally running in because he wanted to get changed and go right out."

The manager also joked that Bieber doesn't have much time left to keep wearing his saggy pants look.

"I think anyone over 25 can't pull it off -- actually over 20," he said. "He's got one more year."
