Nicollette Sheridan and Michael Bolton’s on again, off-again love affair is off again.  They have broken off their engagement after two years….

More pics after the skip…

….for the second time.  E! Online says the pair dated in the early 90s, beginning in 1992 and lasting until 1997.   They broke up an engagement than and didn’t start dating again until 2005, when Nicollette broke up with yet another fiance!  It seems Nicollette can get engaged, but never married.  Is there a diva problem at play here?

Nicollette was briefly married to actor Harry Hamlin, from 1991 until 1993.  He later went on to marry Lisa Rinna and are still together. 

No reason why the current beau and Nicollette broke up, but I guess more details will emerge soon enough.  Why do you think they did?
