The star has enjoyed a fruitful career since his five-year stint as host of MTV's Total Request Live, and he recently claimed his new job meant all his hard work had ''paid off''.

He said: ''Everything I've done in my career up until this point has trained me for Today - the interviews, the live TV, the live radio - it all gets paid off.

''I was playing in the minor leagues and now I've just been called up to the big leagues. It's amazing that I get to be a small part of the new era and generation of 'Today' - not just to be here, but to be here to help build the future of 'Today' and serve as the bridge between viewers and the show.''
