The 19-year-old heartthrob was apparently feeling well enough Friday night to pull off his fourth and final show at London's O2 Arena, clad once again in his all-white blazer and pants with gold gloves and gold-accented hightops.
"still a little short of [breath] tonight but was an incredible show," Bieber tweeted afterward. "London fans go hard! 4 SOLD OUT O2 shows in a row!! #BLESSED."
"too many blessings to allow the stress in," he continued. "the press made things look nuts but really I have enjoyed London. The fans are incredible."
Bieber concluded: "so while I have seen some crazy stuff it is all smiles. Im gonna get some rest and keep doing what i love. Entertain all of u. thanks."
And the fans would certainly like to thank him back, both the ones who attended Thursday's show and got a major scare when their hero crumpled to the ground mid-song and needed a break for oxygen backstage, and those whom he showed up for tonight.
Bieber retweeted a number of his fans' well-wishes and congratulations, including those from Brad Haugen, who was visiting London from Texas for the week: "what a night. @justinbieber is a rockstar in every sense of the word. feel better JB, glad all is OK. and way to do it for the FANS! #proud."
"4 Sold OUT SHOWS in a Row at the O2 in London and thru all the pressure, the lies, and the BS, @justinbieber u delivered...and Im proud of u" Bieber's manager, Scooter Braun, tweeted Friday.
Braun was the one who informed the waiting crowd last night that Bieber was being attended to by paramedics. "dont believe the bs," he also wrote tonight. "we r here to do our best and give back for our blessings. that is what we are about and that is how we shall remain :)"
Bieber also got a positive shout-out from former Mirror editor Piers Morgan with regard to the teen's run-in with the paparazzi this morning in London. Bieber lunged at a hovering shutterbug who had told him to go back to America, but his bodyguard held him back while he recovered his cool.
"I'm backing @justinbieber in paparazzi-gate," Morgan, an honorary Belieber for the day, tweeted. "That photographer was a revoltingly rude, ignorant, foul-mouthed hooligan."
The Canadian heartthrob has the weekend off, then he's due onstage in Lisbon, Portugal, on Monday.
