Justin Bieber has canceled a concert due to be held in Libson, Portugal on Tuesday.
The Canadian singer, 19, has been in the headlines for all the wrong reasons since performing on the European leg of the "Believe" tour.
The star Tweeted last week about his 'worst birthday' as underage friends including Will Smith's 14-year old son, Jaden, were apparently turned away from London nightclub Cirque de Soir.
Following that, Bieber turned up two hours late on stage for a show at London's O2 arena, which left many fans furious and forced to leave before the singer appeared.
The "Baby" singer then took 20 minutes out of a later London concert on March 8 after fainting backstage and was subsequently hospitalized.
The next day, the star threatened a journalist outside his hotel after the pair exchanged words in a profanity-laden conversation.
British newspapers have reported differing versions of events from the singer's stay in the UK, and he reportedly changed hotels due to his excessive demands at the Langham Hotel. A source of "The Sun" said that:
"Justin’s demands were outrageous. He huffed when he couldn’t stay in The Langham’s £5,000-a-night Infinity Suite because it was booked. He also sent back two white Rolls-Royces that had been put on to ferry him around because they were the ‘wrong’ shade of white. He demanded Maybach motors instead."
The show in Lisbon was canceled due to 'unforeseen circumstances' according to an official statement, but a newspaper in Portugal cites 'insufficient demand' for the cancellation.
