Justin Timberlake is continuing his bachelor party in Mexico.

The 'Trouble With The Curve' actor - who is engaged to actress Jessica Biel - kicked off the celebrations in the Surrender Nightclub at Encore Las Vegas with a group of pals on Thursday (20.09.12) before jetting to Cabo San Lucas on Friday (21.09.12) for more festivities, according to E! News.

Justin and Jessica are reportedly planning to wed in Italy in October and Jessica has been busy planning every detail of their big day.

A source said ''Jessica has claimed she is too busy to plan a wedding but she actually has been very involved in all the details, like every bride.''

Wedding planner Diana Sorenso recently planned some nuptials at 19th century boutique hotel Palazzo Margherita and claims the star-studded nuptials will be held there.

She said: ''I've heard the wedding will be intimate, in the palm-tree lined outdoor garden area, just aside from the stunning black bottom pool and giant pergola,

''There will be flowers galore and it will be extremely elegant - the most stunning the palazzo has seen yet.''

Those expected to attend include Amy Adams, Ellen DeGeneres and Justin's former *NSync bandmates and guests won't have to spend any money as the generous couple are paying for everything.

An insider explained: ''Justin and Jessica plan to pay for the entire trip for all their guests and help. That includes private jets, five-star hotels and rental homes, plus food fit for a palace.''
