Justin Bieber's 'Believe' Tour has not been going as well as he must have thought it would do, with his recent behaviour during the UK leg of his tour rousing some harsh criticism from the media - but he was on hand last night to get his tour back on track and really stick it to all the naysayers after performing at a sold-out concert in Portugal, at the same concert-venue where he has reportedly been forced to cancel his follow-up concert due to poor ticket sales.

The Pavilhao Atlantico stadium in Lisbon was, according to TMZ, only able to shift 60% of the tickets for Tuesdays (March, 12) performance, with the Bieber management claiming the cancelation was due to 'unforeseen circumstances.' However Bieber's manager, Scooter Braun, has since told the celebrity website Gossip Cop that both shows were in fact sold out, but he was forced to pull out of the follow-up gig because of worker disputes related to 'issues with load out,' referring to the time given to break down the stage and all the equipment from a show.

Justin Bieber, in a gas mask... No, we're not sure why, either...

Just to stick it to all those haters, whom the Canadian pop sensation considers a constant threat to his career, he posted a number of Twitter updates and Instagram posts from last night's performance in Portugal. The singer tweeted after the performance saying 'PORTUGAL was RIGHT TONIGHT!! #SOLDOUT #BELIEVEtour,'before posting another Tweet thanking the fans that came out for the night and then posting an Instagram picture of a packed Pavilhao Atlantico. Take that haters!
