Justin Timberlake gets a fetching 70s porn star makeover for his latest movie.

The Sexy Back star gets to prance around in a curly brown wig and matching handlebar moustache as athlete Jacques Granden in The Love Guru.

We also get to see his Trousersnake squeezed into some skin-tight speedos in the comedy, which also stars Mike Myers and Jessica Alba.

The Love Guru is set for a summer release.
