When you are dating a man for money, the last thing you want to do is be caught cheating. Katie Lee Joel obviously did not graduate from the Heather Mills School Of Gold-Digging.

Of course there have been rumors of an affair. Katie Lee has been accused of knockin’ boots with Israeli designer Yigal Azrouel. However, Katie claims the rumors are “mean-spirited” and “untrue”.

First of all, when you cheat, do NOT get photographed engaging in an intimate moment with the man you are having an affair with. Last month, Katie Lee Joel was photographed dancing intimately with the fashion designer.

It has only been five years that Katie Lee has been married to Billy Joel and already she’s straying? Katie Lee begs to differ as she has taken to her Twitter page to knock down reports of cheating.

Her rep tells Us Weekly magazine, “They’ve just been friends – purely platonic.”

So, the big question is, why hasn’t Katie Lee gotten herself knocked up? Rumors have been that Billy and Katie Lee have been duking it out over starting a family. But…her rep also insists that nope…there are no issues.

Mmmhmmm. That means, there is trouble in paradise.
