The 'Suit & Tie' singer may well be having a sing-off with his pop rival Robin this weekend.

Justin Timberlake and Robin Thicke are widely rumoured to be planning a sing-off to celebrate Pharrell Williams' wedding celebrations this coming weekend.

The two US stars are reportedly both expected to perform on stage at the wedding bash in Miami this Saturday (12th September), with tabloids claiming the pair are planning a special performance.

According Page Six, a host of stars including Jay-Z and Gwen Stefani are also expected to attend the event, to celebrate Pharrell's marriage to Helen Lasichanh back in August this year.

The pair wed in secret over the summer, and already have a song together named Rocket Man.

Robin and Justin have often been compared for their similar styles of music, although neither has commented on the widespread rumours of a sing-off.

Justin Timberlake announced plans to bring his '20/20 Experience' tour over to the UK in spring next year, with five shows started with a gig in Sheffield on 30th March.
