A flat out denial comes from Dancing with the Stars runner-up Katherine Jenkins, who says she did not have a fling with David Beckham.
After the rumors spread online, out-of-control fans of the hunky soccer star and his wife, Victoria, threatened Jenkin's life on Twitter.
"That [blank] is getting cut if David and Posh split."
Victoria Beckham is reportedly "seething over the affair rumors."
A spokesperson for David Beckham tells INSIDE EDITION: "Unfortunately, we have to deal with this type of nonsense on Twitter. One minute David is dead, then the more scurrilous rumors. There is no truth to any of it."
