Only if you ignore the fact they've been 'coming for' Justin constantly for years. One of Drake and Josh supported my friends tweet of Bieber abuse once and then we spent the weekend fighting with angry Bieber fans. Fun times.
It'll be kind of weird since most of the children who watch Nick now probably aren't familiar with their TV show. I know they did a Christmas movie, but I think that was about 5 years ago. The audience they used to have is probably in their mid to late teens now. I don't think many will tune in unfortunately.
