Nicollette Sheridan is Back on the Market

Nicollette Sheridan and Michael Bolton have split up for the second time since they began dating in 1992, dated for five years, split up, got back together in 2005, and becoming engaged in 2006. 

Their rep tells People:

• 'Nicollette Sheridan and Michael Bolton have amicably ended their engagement.  They appreciate your respect for their privacy in this matter.'

No word yet on why they called it quits, but judging from this pictures form last year, it certainly wasn't on account of bad sex.
