Justin Bieber Believe Tour: Performs at Portugal, Hits Out At Critics, Find Out The Real Reason For Tour Cancellation

Pop sensation Justin Bieber has hit back at critics as he took to the stage in Portugal March 11 as part of his "Believe" world tour. The singer has been under constant attack since last week for reasons as different as wearing a gas mask, spiked yellow hat, not wearing a shirt, getting booed by fans for arriving two hours late, getting into a fight with a photographer and his meltdown at the London concert.

He put all the negative things that happen over the weekend to rest and was up on stage. He Tweeted, "PORTUGAL was RIGHT TONIGHT!! #SOLDOUT #BELIEVEtour" after he finished his concert.

He also added on his Instagram account a photo with the message that thanked the crowd, it read, "thanks to all the fans...the beliebers tonight. incredible show!"

His manager, Scooter Braun, denied rumors that Bieber's meltdown was because of the pressure of fame, EntertainmentWise reported.

Many stars like Will Smith, Harry Styles and Will.i.Am have reached out to the young singer.

It was reported that Bieber vowed not to come again to the UK because of what he went through. But the 19-year-old singer put these reports to rest as he tweeted that UK Beliebers were "incredible" and  he "will be back. and i will see u again. and I am grateful for all of u. U are what made some of the other stuff ;) worth it".

TMZ reports that his Portuguese concert was cancelled not because of him being sick or his meltdown but because the ticket sales for the concert were low and it was a "business decision" to cancel the show.
