There comes a time in the career of every teen idol when he wants to be treated as a hip adult. That time apparently has arrived for 18-year-old Justin Bieber, who tweeted to his fans on Wednesday: so the word is out...it is true...im Performing and HOSTING Saturday Night Live on FEB 9th!!! GET READY! #NothingisOffLimits #BELIEVE Writers immediately assumed that the show will offer at least one sketch that will refer to photos taken at a party showing the young singer apparently smoking a joint. Indeed the gossip website TMZ reported that Bieber has given the SNL staff no-holds-barred freedom to write what they will, and presumably that also includes spoofing the reported break-up of his longtime relationship with Selena Gomez. However, RadarOnline, another gossip website, quoting an unnamed insider, reported on Wednesday that Bieber's team, particularly manager Scooter Braun, is absolutely livid about Bieber's recent conduct. Everything Justin does directly effects Scooter's career and his success. He feels like Justin should know better than to get caught up in all this, the source said.
