(Cover) - EN Showbiz - Justin Timberlake will reportedly perform a "tongue-in-cheek" wedding dance for Jessica Biel.

The singer is expected to marry actress Jessica in Italy this week.

Justin has apparently been practising a routine with his ushers to 'N Sync's track It's Gonna Be Me.

"Justin has been working on this for months. Jessica used to love the track growing up and he wants it as a special treat," a source revealed to British newspaper The Sun.

"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."

Justin and Jessica got engaged in December last year after five years of dating.

Yesterday reports emerged that the couple's wedding day is likely to be taking place this week.

Sources told the New York Post the couple have chosen a tiny town near the city of Naples for their nuptials, which is a location that "means a lot to both of them."

"The wedding is happening outside of Naples in a tiny town this week. It is their favourite place, a location that is very special to them. There will be a few hundred guests, and the maid of honour will be Jessica's long-time best friend, Lindsay Ratowsky," the source told the New York Post.

"A private plane was flown out of New York to take guests to Italy including both their publicists. But the event has been shrouded in a lot of secrecy, and not even the guests were told the exact location or day of the wedding before they left." (C) Cover Media
