When you're dad is a perv, it just kinda runs in the family!
According to reports, a 22-year old woman has been having "inappropriate sexual relations" with Billy Bob Thornton's son, Willie.
The woman's ex-boyfriend apparently became jealous and then called the LAPD, informing them his former lady was having sex with a minor.
As y'all know, it's illegal for an adult to have sex with anyone under 18, even if consensual.
Sources say the Thorntons have been cooperating with the LAPD sex crimes unit's investigations.
What was that ho thinking???
We're sure her family is very proud!
