SPLIT!!!!! Ann Coulter and Andrew SteinWhenever a longtime celebrity couple breaks up, it causes us to call into question everything we believe about relationships. When Padma Lakshmi and Salman Rushdie broke up, we felt hurt, and confused. It was the same with Sean and Robin Wright Penn. And then today, we read that Norah Jones and her longtime boyfriend and collaborator, Lee Alexander, split up. If they can’t work it out, we said to ourselves, then what hope is there for the rest of us? In this sort of climate, we wondered what celebrity couple would be next. Please God, we thought, please don’t take Jon Bon Jovi and his high-school sweetheart, Dorothea. But it was even worse. Today, “Page Six” reported the demise of the couple of the century, Ann Coulter and Andrew Stein.
