Justin Bieber: 'Never Say Never' premiere, 'Dougie' dance lessons for Regis Philbin

Watch out, Kourtney and Kim -- it's Justin Bieber's chance to take New York, as he does the rounds for his 3-D movie, "Never Say Never," which screened in the Big Apple on Wednesday.

Later that night at the New York Knicks-Dallas Mavericks game at Madison Square Garden, Bieber got cheers and boos from the crowd, chatted with Chris Rock and got a handshake from Knicks fan Spike Lee, who'd also attended the "Never Say Never" premiere with his son, Jackson.
Then on Thursday, the Biebs taught the Dougie dance to Regis Philbin and Kelly Ripa (watch it above around the 12:30 mark), did his President Obama impersonation (around 11 minutes in) and shared advice from Usher about girls -- that sometimes you have to let them win. The singer will be on "Live! With Regis and Kelly" on Friday as well.
All this after premiering "Never Say Never" in Toronto on Tuesday -- Bieber is Canadian -- and appearing on "Much Music," where he revealed he got "10,000 or something" Twitter messages a day, and the host revealed she cried through most of his documentary/concert film, then gave him tips on how to smile.
