American actress-singer Lindsay Lohan has dismissed reports that she is dating Scottish actor Gerard Butler.

The Mean Girls star is alleged to have enjoyed a number of flings since splitting from DJ girlfriend Samantha Ronson earlier this year. She was linked to The Ugly Truth star Butler after they were allegedly spotted kissing at the grand opening of a luxury beach resort in Morocco, said a report.

But she insists that the rumours were untrue and admits that the inaccurate media reports constantly keep her smiling.

"One minute I'm dumped, the next I'm dating a model, now Gerard. Who has the time? It keeps me laughing," Lohan said.
