30 Seconds To Mars frontman Jared Leto has denied that he is responsible for the break-up of pop strumpet Jessica Simpson's relationship with Dallas Cowboys quarterback Tony Romo.
Leto's manager, Jason Weinberg, slammed a report in US tabloid The National Enquirer claiming that he had a dalliance with the elder Simpson sister during her relationship with Romo.
"There is no truth whatsoever to the article," Weinberg told American magazine Us Weekly.
Simpson's new brother-in-law, Fall Out Boy bassist Pete Wentz, refused to comment on the allegations. Wentzy told American Idol host Ryan Seacrest in a radio interview that:
"I don't know anything about what's going on with them. I'm so busy clearing up my own rumours!"
