Obnoxious but waggishly charming tech mogul Elon Musk is 43 years old and getting divorced for the third time. There's a twist this time because the woman he's divorcing is the one he divorced last time. It's like this. Elon married one woman, Justine Musk, and had a bunch of kids with her, then divorced Justine to marry an actress, Talulah Riley, then divorced the actress, then remarried the actress, and now they're divorcing again.
