Rob Lowe files lawsuit against his former nanny and chef.

This morning in Moms Are Talking About, we told you about Rob Lowe filing a suit against his former nanny and personal chef. In court documents, he claims the nanny spread "malicious lies" about their family, did drugs on the job, and reported to work under the influence. He also claims that the chef had been having sex in their bed with strangers while they were out of town, as well as stealing prescription drugs, food, and even their mail.

Whoa. What's the worst thing you've ever caught your kid's babysitter doing?
