Before this thread gets silly.. more than meets the eye on this story.
From I'm reading elsewhere... this isn't a case of married for 20 years, husband dies, widow re-marries two years later. Reads like they got married, then separated with the wife still managing husband's music career. Otherwise, living separate lives. It may not be a straight up case of "two years omg so soon."
Honestly, not sure of details... personally, I don't care and won't be researching. Only posting as a heads up before people start making shit up.
