OTRC: Justin Bieber short of breath during concert, 'enjoyed London' despite media frenzy

Justin Bieber's self-described "rough week" in London came to a close on Friday, March 8, when he performed his fourth concert in the city and said he was still short of breath during his performance.

The singer, who fainted during his concert at the O2 Arena on March 7, Tweeted to his followers, "Still a little short of breathe [sic] tonight but was an incredible show. London fans go hard! 4 SOLD OUT O2 shows in a row!! #BLESSED."

Bieber had previously complained of breathing problems while performing on March 7, before he fainted backstage. He was given oxygen, continued the show and was later hospitalized to get checked out. The reason behind his breathing troubles has not been explained.

The 19-year-old also Tweeted that he enjoyed his time in London despite a few brushes with the media, which included arguing with a paparazzo on Friday, March 8.

"Too many blessings to allow the stress in," he wrote on March 8. "The press made things look nuts but really I have enjoyed London. The fans are incredible."

"So while I have seen some crazy stuff it is all smiles," he added. "I'm gonna get some rest and keep doing what i love. Entertain all of u. thanks."

Bieber also received media attention for Tweeting about his "worst birthday" on March 1. He later deleted the Tweet. Rumors circulated that the bad birthday celebration was the result of his entourage getting into an argument with the staff of a nightclub and reports claimed that Bieber attempted to get minors into an 18-and-over club.

However, the singer explained the situation on his Instagram page on March 3.

"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," Bieber wrote in a post on his Instagram account on March 3, referring to reports that claimed he tried to get Will Smith's son, 14-year-old Jaden Smith, into a night club.

"2nd I love how the club wanted to give the press another reason to why we didn't stay at their weak [expletive] club so they wouldn't look bad for me walking in and right back out," he added. "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."
