Will Smith acted as a mentor for Justin Bieber during his stint in London recently. The legendary entertainer doesn’t seem to have performed his mentor tasks well though, as Bieber annoyed nearly everyone he came into contact with.

There was the 2-hour delay to his London 02 show, which meant a lot of kids and their parents had to leave to get the last train home. There was, of course, that paparazzi that Biebz threatened to beat up due after some mean words. Then there was the fan who spend £330 to meet her hero, then having to wait 3 hours for the bratty star, who eventually only showed up for 15 seconds. Oh and he totally missed out on his scheduled ITV interview. Great job, Will; it’s all your fault now. Angie Simpson – mother of support act to Bieber, Cody Simpson – said: "Will has been helping Justin out a lot, mentoring him and offering him guidance. He’s someone who is used to this level of scrutiny and it has helped having him around. Justin is an adult and has a very strong, loyal and professional team around him, but it is hard for anyone to come under such pressure."

It would appear as though Bieber’s problems are worldwide, too. He’s had to cancel a show in Portugal. “Due to unforeseen circumstances, Justin Bieber was forced to cancel the second performance in Portugal, March 12,” said the website for Pavilhao Atlantico, which added that the “Canadian singer is eager to play for the Portuguese fans on March 11.”
