X-Men actress January Jones refuses to give into the medias fascination of finding out whe father is of her one-year-old son Xander is. Jones sat down with the New York Times where she joked about her personal life but still refused to give into answering who her baby daddy is.

Jones tells The Times, “That’s my son’s business...It’s not the public’s business.”

Speculation is that X-Men costar Michael Fassbender is among the handful of men speculated to have fathered the adorable 1-year-old boy. According to New York Daily News, along with Fassbender, director Matthew Vaughn and actor Xander Berkeley are the others. However, Vaughn has denied ever having a sexual relationship with the blonde beauty.

Jones notes, “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.’ ” She adds, “Women should have lots of secrets.It’s our right to have secrets. Otherwise, what would we write in our memoirs?”

Jones was previously the subject of backlash after she was spotted with Miley Cyrus' fiance Liam Hemsworth. Rumors that the two were hooking up causing Cyrus and Hemsworth to take a break surfaced shortly thereafter. Currently Jones can be seen starring as Betty in Mad Men.
