James Corden made a trip to visit the Backstreet Boys in Las Vegas recently to provide "tired" Brian Littrell with a night off . . . even if he didn't really want it. As a way of thanking the band for their recent performance on The Late Late Show With James Corden, James decided to drop in at Planet Hollywood, where they currently have a residency, to step into the shoes of one of the guys for one night only. In typical Corden style, James quickly took over the whole thing, changing the choreography, putting himself front and centre, and even suggesting that the rest of the band "disappear for the rest of the song". Of course, when he finally did slip into his all-white outfit and take his place on stage, James definitely put in a "Larger Than Life" performance, even if he didn't have the stamina to be a BSB for real. Watch him living out his boy band dreams above, then take a step into the BSB time machine as you enjoy their evolution from teen dreams to hot dads.
