A bar owner in Illinois is fighting with Justin Timberlake's lawyers over a pricey autograph-signing appearance he has scheduled for the star.

Sharky's Billiards owner Joe Piagentini claims a promoter assured him the My Love singer would be appearing at the bar on March 13 after he paid him a $25,000 fee.

Timberlake is performing in the Chicago suburb of Rosemont and is supposedly scheduled to attend the autograph-signing session after his gig.

But one of the star's Los Angeles-based lawyers, Gary Stiffelman, insists the singer is not going to show because he hasn't discussed the appearance with anyone or even heard of Piagentini.

Meanwhile, Piagentini insists the appearance is still a "go", although he hasn't sold any tickets yet.

According to Fox News, the tickets are being advertised on websites for $100 each.
