It's a big birthday for Jennifer Lopez. She's celebrating the big 4-0 today. Other people who will be blowing out candles this fine Friday: Broadway star Kristin Chenoweth is turning 41. Anna Paquin is 27. Director Doug Liman turns 44. Director Gus Van Sant is turning 57. Billionaire investor Nelson Peltz is 67. Artist Alex Katz is turning 82. Senator Claire McCaskill is 56. Governor Charlie Crist of Florida is 53. Barry Bonds turns 45. Retired basketball stars Rick Fox and Karl Malone are turning 40 and 46, respectively. Michael Richards of Seinfeld fame is turning 60. Actor Dan Hedaya is 69. And Wonder Woman—actress Lynda Carter—celebrates her 58th birthday today. Weekend birthdays after the jump.

The stories we recounted last week about the abusive working conditions at the estate of Nelson Peltz (see here and here) weren't the first complaints directed at the billionaire investor. Last month, James Turowski, who says he worked as a bodyguard and chauffeur for Peltz, filed a discrimination lawsuit against his employer. Turowski says he was working for the Peltzes when he sustained a serious head injury, and he ultimately had to be hospitalized for several weeks as a result. When he returned to work, however, he was almost immediately fired, a violation, he claims, of city and state employment laws as well as the Americans with Disabilities Act. Last week, Peltz's attorneys filed papers to move the case from state court to federal court. But Peltz's legal team may have more on its plate in the near future. We hear several former employees of his estate are now looking into filing a class action suit over the treatment they received working at Peltz's Westchester mansion. In the meantime, you'll find Turowski's suit after the jump.

We have some new—and disturbing—information on the house of horrors in Bedford occupied by billionaire Nelson Peltz and his wife Claudia. (If you missed yesterday's installment, go here.) We've made contact with several other people who worked inside the home in the past, and their stories, which are just as outrageous as the ones we'd heard previously, make it clear that the Peltzes may very well be the scariest couple to work for in the tri-state area.

Billionaire Nelson Peltz remains one of the most famous takeover artists in America: In recent years, the corporate raider (or "activist investor," as he prefers to be known) has battled for control of Wendy's, Heinz, and the candymaker Cadbury Schweppes. His hard-charging approach and tendency to ruffle feathers isn't just restricted to his professional life. Life inside Peltz's vast estate in Bedford is just as vicious, we hear, and the staff at the estate is subjected to such a dizzying amount of abuse, the Peltzes may be the worst family in America to work for.
