Timberlake 'plans summer wedding' to Biel

US popstar Justin Timberlake could be set to join the throngs of grooms-to-be looking to organise the perfect stag night this year, according to media reports.

The singer is rumoured to be planning a summer wedding with long-term girlfriend Jessica Biel and is keen to hold the ceremony in Italy.

However, the 27-year-old appears to have put any stag do plans on the backburner for now, instead turning his attention to landing the ideal diamond ring for his potential bride.

A source told the Metro: "They both like the idea of marrying in Italy in the summer."

"Justin was really taking his time looking round the rings. He made the staff get a couple out of the cabinets so he could properly look at them," a witness added.

It remains to be seen whether Timberlake's stag night will be a glitzy affair or if the star will opt for a more toned-down event.

Earlier this year, fellow singing sensation Fergie held a joint stag and hen night with fiancee Josh Duhamel because the pair were keen to spend as much time together as possible.
