Justin Timberlake - Timberlake And Biel Fuel Split Rumours

Pop star JUSTIN TIMBERLAKE and girlfriend JESSICA BIEL fuelled reports their relationship is in trouble after they failed to show up at a casino opening.

The couple, dating since 2007, has recently been dogged by rumours they plan to split, with a source telling U.S. newspaper The Chicago Sun-Times: "Things are not going as smoothly as (Biel and Timberlake) would want people to think they are."

The stars then added to the speculation when they failed to deliver a scheduled promotional appearance at the launch of an Indiana Live Casino in Shelbyville, Indiana on 13 March (09).

And their absence infuriated many members of the 8,000-strong audience.

Guest Marian Flemming says, "It was ridiculous. They promised us that Justin and Jessica were going to be here, so we came down to check out the new casino and had hoped to see the two stars. When they did not show up, we simply felt cheated."
