Los Angeles - Justin Timberlake is to perform a dance to Jessica Biel's favourite 'N Sync song at their wedding.
Justin has been rehearsing a surprise routine to his former band's track It's Gonna Be Me with his best man and ushers as he prepares for his nuptials to the Total Recall actress.
A source told The Sun newspaper: "Justin has been working on this for months. Jessica used to love the track growing up and he wants it as a special treat.
"It will be very much tongue-in-cheek. There will be loads of exaggerated boy band moves and poses. She's going to love it."
The 30-year-old pop star - who sold more than 50 million albums with 'N Sync - got engaged to Jessica, 30, last December and the pair are tying the knot in Brindisi, southern Italy, at the weekend.
Celebrations began earlier this week as guests enjoyed a low-key drinks reception near Naples on Tuesday and watched an impressive fireworks display on Wednesday.
The couple splashed out in order to celebrate their special day with all their friends and family, hiring a private jet to fly guests - including Saturday Night Live comedian Andy Samberg and music producer Timbaland - to Italy for the ceremony.
