Not much of a surprise. Everything about her behavior reminded me of the actress Kaley Cuoco, who went on for ages "proving" to the public how much she loved her husband and how he was her world, and so on. And very quickly I began to feel she was "proving" it to herself, because deep down she knew it wasn't working.
I guess at least Yolanda got more years, and plenty of PR and a TV gig, out of it. Personally I never felt like David Foster (whom I've always disliked ever since he used to smarm on American Idol) had much love for her any time I saw them onscreen together. He looked bored. Not that I can blame him...
