Cityfile: New York's Most Notable and Influential

• Madonna's kicked boytoy Jesus Luz to the curb and is thrilled to be single again, reports Britain's Daily Mail based on the things she's been telling fans on Twitter. But as the Times reminds us today, lots of celebs only pretend to use Twitter, so you don't have to give up hope entirely just yet. [DM]

• How did the press know Chris Brown was in Miami with Rihanna last weekend? He told them so, silly.

They said it wouldn't last, and, well, it didn't. After repeatedly denying her marriage was on the rocks, Ivana Trump issued a statement this morning confirming that she and Italian playboy Rossano Rubicondi are divorcing. Ivana actually says she filed for legal separation three months ago, which means the couple was together for just four months following their lavish nuptials at Mar-a-Lago back in April. (This also sets a new record for the former wife of the Donald: Her second marriage to Riccardo Mazzucchelli lasted a full 20 months.) So what caused the split between the 59-year-old grandmother and her 35-year old third husband? It was just a matter of geography, apparently. Ivana says Rubicondi wanted to "live in Miami and work in Milan," but she's a New Yorker who would rather go to "Miami for weekends, and Milan to see friends and go shopping." And, really, how could a couple survive something as serious as that?

Two weeks ago the news surfaced that Viacom chief Sumner Redstone and his second wife, Paula Fortunato, were divorcing after five years of marriage. Much was made of Redstone and Fortunato's 39-year age gap and the couple's pre-nup, which will provide Fortunato with a $5 million fortuno for the five years she spent by the not-so-healthy billionaire's side. But she's hardly the only one who has been married to someone who could easily pass for her father or granddad. After the jump, a list of famous New York couples and their equally famous age gaps.

The price of marrying someone much younger and prettier than yourself is that they might not be the sharpest knife in the drawer. Uber-cougar Ivana Trump can laugh about it, though, as she did when her fourth and current husband, thirty-something Italian Rossano Rubicondi, put his lifejacket on the wrong way during an emergency drill aboard a Mediterranean cruise. "If something happens, you're floating facedown," she admonished him. Given Ivana's propensity for falling down on yachts, someone needs to keep their wits about them! [Page Six Magazine]
