Today's entertainment news: Kim Kardashian assaulted with powder

A woman threw cooking flour on Kim Kardashian in the lobby of a West Hollywood hotel where the television personality was hosting an event touting her new fragrance line. During the incident, the attacker shouted: "Fur hag!" Police were called in to the London Hotel shortly before 8pm Thursday. Kardashian told the deputies she did not want to press charges against the woman, and a non-criminal battery report was taken. Paramedics were called to the hotel, but Kardashian refused medical treatment and instead went to a private room, removed the powder from her hair and clothing and returned to the event. Later in an interview with TMZ, Kardashian called her attacker a "bully" and says she tried to "laugh it off" by returning to her hosting gig, claiming she didn't want to disrespect the people who put the event together. "If you're trying to promote non-violence towards animals, why are you trying to be violent towards humans?" she said. Madonna recalls emotional recording Madonna told The Sun on Friday that she was close to tears when she returned to the recording studio for her new album MDNA . "It's amazing to be back in music. I like the intimacy of a recording studio and songwriting," she told the paper. "It was nice to have the simplicity of songwriting after three years of writing a script and directing and editing and talking about my film, to sit down and play my guitar and sing a song. I almost cried." New Mozart piece performed A piano work that experts attribute to Mozart as a child prodigy was performed for the first time on Friday since it was found last year after apparently being left in an attic for centuries. The lively 84-bar passage - marked "allegro molto" or "very quick" - was played on the composer's piano in a room of his Salzburg home by the virtuoso Florian Birsak. The Mozarteum Salzburg Foundation, which staged the event, said the manuscript was found last summer as part of a 160-page book of handwritten piano music as the musty attic of a house in Tyrol was being cleared from centuries of detritus. Part of a collection of notes from a village music teacher, the book was dated 1780 - 24 years after Mozart was born - and the manuscript played on Friday bore the name "Del Signore Giovane Wolfgango Mozart", Italian for "Mr Wolfgang Mozart Jr". From the style of the composition, Hermann-Schneider attributed it to Mozart at around the age of 11. * AP Houston's full autopsy to offer details Whitney Houston's full autopsy report may offer more clues about whether the singer suffered a heart attack before her drowning death, officials said on Friday. The full report, which is expected to be released in a few weeks, may include test results and physical descriptions of the singer's heart. Her death has been ruled an accidental drowning, with heart disease and cocaine use listed as contributing factors. "We are saddened to learn of the toxicology results, although we are glad to now have closure," Patricia Houston, the singer's sister-in-law and manager, wrote in a statement to the Associated Press on Thursday. * AP The Rock returns to WWE Catchphrase-chanting, diehard pro wrestling lovers are revved up about the return of one of their biggest superstars. Dwayne Johnson is setting aside a successful film career to return to wrestling, where he is known as The Rock. He is set to return to the WWE ring for his first WrestleMania match since 2004 on an April 1 card against the former champion John Cena. "I came back to put on the biggest match of all time," Johnson said. "That's all I want to do. There's no one I can do that with right now other than John. He's far and above everyone else in terms of popularity." Johnson reined in that top spot at the end of the 1990s and the early part of the last decade before embarking on an impressive run in Hollywood. His current film, Journey 2: The Mysterious Island , has performed well at the box office worldwide. * AP Follow Arts & Life on Twitter to keep up with all the latest news and events
