Nicollette Sheridan and Michael Bolton by Steve Granitz/WireImage.com
After announcing their engagement in March of 2006, Desperate Housewives' Nicollette Sheridan and singer Michael Bolton have decided to end their relationship.

Sheridan's rep Nicole Perna told People that the pair "have amicably ended their engagement," and asked that the public "respect their privacy in this matter."

Sheridan, 44, and Bolton, 55, actually dated in 1992 for five years and rekindled their romance in 2005. After many lovey-dovey outings, the couple seemed happily smitten and announced their plans to wed.

Bolton's reps have yet to comment on the duo's split. - Erin Fox
