London, March 14 (IANS) A representative for Justin Timberlake has once again rubbished reports that the popstar and his actress girlfriend Jessica Biel have split.

The couple's relationship came under scrutiny in recent months with online gossips saying that a break-up is imminent.

Timberlake and Biel shrugged off the rumours with a string of public appearances and made a romantic trip to Switzerland to celebrate Beil's 28th birthday, reports dailystar.co.uk.

But the rumours of troubled relationship again kicked off when the 'SexyBack' hitmaker was photographed partying with a scantily-clad dancer at Tao nightclub in Sin City.

The spokesperson for Timberlake insists there's no truth to rumours and said: 'They're not breaking-up.'
