Kim Kardashian skips out on sister Kylie's bash; Madonna wears diamonds on teeth at concert appearance KIM Kardashian skipped out on lil' sis Kylie's Sweet 16 party, avoiding growing family dramas to stay home with baby North. Meanwhile, Madonna attended a classical music festival wearing a set of diamond teeth while Lindsay Lohan reportedly threw a temper tantrum when she couldn't get co-star James Deen on to a talk show with her. Oh, no, is it all falling apart for the Kardashians? Charles Saatchi reportedly threatened to harm himself if his wife Nigella Lawson didn't call him., as the public split intensifies. Picture: Daily Mail Source: Advertising guru Charles Saatchi is said to be begging his wife Nigella Lawson to take him back after their recent divorce, with a British newspaper even reporting that he has come close to harming himself. Friends of Lawson's have told the newspaper that Saatchi appears to have become unhinged since their split, bombarding his now estranged wife with texts and phone calls, and making threats to harm himself if she doesn't call him. "Charles has been texting and phoning Nigella endlessly," one source said. One minute he's pleading, the next bullying. Her silence has been driving him crazy. Lawson, 53, and Saatchi, 70, who are said to be worth nearly $250 million, divorced last month. Their split was set in motion in early June when a photographer caught Saatchi grabblng Lawson by the throat during an argument outside a London restaurant. Madonna has shown a penchant for grills recently, and posted this picture to Instagram. When it comes to fashion, Madonna has long been ahead of the curve, but her latest accessory leaves just a little bit to be desired. Attending a classical music festival in the South of France, Mads debuted an impressive set of diamond grills affixed to her teeth (her fellow symphony lovers must have really enjoyed that look), which made her appear infinitely more like Flavour Flav than one of the world's richest entertainers (Mads posted a photo to Instagram of her chomping down on some sort of er, sword). The grill apparently cost an arm and a leg, featuring some 24 diamonds and an open-teeth design, which shows her real teeth below. Madonna was in the country with her French dancer boyfriend Brahim Zaibat to see close friends, concert pianist sisters Katia and Marielle Labèque perform. She certainly received a much warmer reception in France than she has had in Russia recently where authorities are after her for performing on the wrong visa, and also for "promoting" homosexuality. Sheesh. It seems the fresh out of rehab actress threw a monumental tantrum when she couldn't get her porn star co-star James Deen in the audience (Deen appeared alongside Lohan in the train wreck that is The Canyons).
