It doesn't get much worse than having an extramarital affair.
This holds true whether you are an actor, a professional athlete or a grocery store clerk.
But a few celebrities have gone ahead and taken that extra awful step... by allegedly having an affair with their family's nanny!
As you can see below, these stars range in talent and cover all industries. But all sort of suck if the accusations are true:
Arnold Schwarzenegger clearly comes in first (or last, depending on how you look at it). He cheated on Maria Shriver AND had a child out of wedlock with his nanny/maid.
Ben Affleck's rep denies this rumor. But multiple outlets have claimed he started sleeping with nanny Christine Ouzounian while separated from Jennifer Garner.
Jude Law (the father of five with three different women) admitted to a fling with nanny Daisy Wright in 2005. It ended his relationship with Sienna Miller.
The late comedian's second wife, Marsha Garces Williams, actually worked as a nanny for Williams and his first wife, Valerie Velardi, when their son Zak was a toddler.
