The "Mad Men" star has kept the identity of her son Xander's father a mystery, prompting speculation ranging from Jason Sudeikis to "X-Men: First Class" director Matthew Vaughn.
And now, Jones is speaking out ... but she isn't naming names.
"That's my son's business," she tells the New York Times. "It's not the public's business."
Of her personal privacy, the actress adds "Jack Nicholson once told me: 'You should never give your personal life away, otherwise people will pick you apart. They'll never believe in your character.'"
The 35-year-old has plenty to say about keeping secrets. And she has her reasons for them.
"Women should have lots of secrets," she says. "It's our right to have secrets. Otherwise, what would we write in our memoirs?"
Do you think we'll ever learn who Xander's baby daddy is? Should we even care?
