Jessica Simpson Has Secret Nickname For Tony Romo

Jessica Simpson has a secret nickname for her beau Tony Romo.

The former Newly Weds star apparently calls the Dallas Cowboys quarterback her FBD — future baby's daddy — whenever she talks to her pals.

"She knows he's not ready to get that serious, so she's playing it cool," a source tells Star magazine. "Tony doesn't know, of course."

Simpson, 28, recently described Romo as the "perfect guy."

"I just told him today, 'You're the love of my life,'" Simpson told People magazine in August. "I don't really ever say that to anybody."

She also revealed that she had changed all of her email addresses and telephone numbers so that no one from her past -- specifically ex-boyfriends -- could get back in touch.

She said, "I don't want anybody that's been in my life [before] in my life anymore.

"I don't even want them to have any way of contacting me."
