Bieber collapsed on stage on Thursday and needed oxygen, then on Friday got into a shouting match with a photographer and had to be dragged away by his security team.
But in Friday’s show, the Biebs showed no signs of stress, performing a flawless show to an excited crowd. Justin tweeted later, "Still a little short of breath tonight but was an incredible show. London fans go hard! 4 SOLD OUT O2 shows in a row!! #BLESSED"He also wrote, "Too many blessings to allow the stress in. The press made things look nuts but really I have enjoyed London. The fans are incredible."
With his stop in London behind him, Bieber's Believe tour will next head to Lisbon, Portugal.
Singer Justin Bieber is finally leaving London behind him after a rough week of a bad birthday, illnesses and a run-in with paparazzi… but at least he ended his “Believe” tour on a high note.
