A spokesperson for Justin Timberlake has trashed reports claiming the actor has split from Jessica Biel.

The couple's romance was speculated to be sailing in troubled waters after the singer was spotted with another woman in Las Vegas.

The SexyBack hitmaker was snapped partying with a scantily-clad dancer at Tao nightclub in Sin City, the Daily Star reported.

But a representative for the star laid the rumours to rest, after telling Hollyscoop.com, "They're not breaking up." (ANI)
