Fears Kim Kardashian's medical records were snooped on, Guy Ritchie and Madonna meet for son's Bar Mitzvah Kim Kardashian has maintained a low profile since the birth of her daughter by Kanye West. Picture: Mehdi Taamallah/AFP Source: AFP THE hospital where Kim Kardashian gave birth has sacked staff for allegedly looking at patient medical records. Meanwhile, Demi Lovato takes a swipe at Justin Bieber on the X-Factor and Fergie from the Black Eyed Peas files to have her name changed - she's really called Stacy Ann. Six medical workers have been fired for allegedly trying to access medical records from Cedars-Sinai Medical Centre, the hospital where Kim Kardashian gave birth. Hospital officials say that medical records for 14 patients were "inappropriately accessed" between June 18 and June 24, days after Kardashian gave birth to her daughter North by rapper Kanye West. According to a statement released by the hospital, four of the six fired were community physicians who had staff privileges, another was a hospital medical assistant, and the sixth was an unpaid student research assistant. A spokeswoman said that all patients involved were alerted of the security breach. Five of the fired workers sneaked a peek at one specific medical record, while the sixth looked at a whopping 14 records. Kardashian's rep has yet to comment, while the new mum has stayed uncharacteristically er, mum on news of her baby daughter. Demi Lovato with fellow X Factor host Simon Cowell in Los Angeles.

The former Disney star (who's now a judge on the US version of The X-Factor), apparently didn't take too kindly to the bad attitude of one of the auditionees. "We don't need another little punk running the streets," she snarled. And though she may not have been directly referring to Bieber, her next sledge was a little less subtle. When a contestant auditioned singing Bieber's hit, As Long As You Love Me, Lovato was said to snigger, "Well finally someone can sing the song the way it was meant to be sung." Lovato, of course, has been best mates with Selena Gomez (Bieber's on/off again GF) for a good 10 years. Madonna and Guy Ritchie split in 2008. Picture: Max Nash/AFP Source: AFP Madonna and Guy Ritchie (who once said that being married to the superstar was like "living in a soap opera") reunited over the weekend in New York... for son Rocco's Bar Mitzvah. The actual ceremony was held at a Kabbalah centre in New York on Saturday, but the entire family spent Friday night having a little pre-party together. Rocco, who was born in 2000, is the pair's only biological child. Madonna also has a daughter Lourdes, 16, and two adopted children David and Mercy. Since their split in 2008, the pair has well and truly moved on. Madonna is now dating dancer Brahim Zaibat and Ritchie has two other children with fiancée Jacqui Ainsley. Fergie on stage during a concert in Paris in 2011. Fergie from the Black Eyed Peas has filed legal documents to have her entire name changed. Fergie (born Stacy Ann Ferguson), has requested her name be changed to Fergie Duhamel. The reasons for wanting to change her surname are obvious (she married actor Josh Duhamel four-and-a-half years ago), but she's said she wants to drop her first name in order to "conform to the first name which she is commonly and professionally known as, and has been for many years." We'd actually forgotten her name was Stacy.
