Jessica Simpson apparently has a secret nickname for beau Tony Romo which she uses with her girlfriends – 'FBD', or 'Future Baby’s Daddy.'
"She knows he's not ready to get that serious, so she's playing it cool," a source tells Star.
"Tony doesn't know, of course."
The Newlyweds star recently described the Dallas Cowboys quarterback as her ‘perfect guy.’
"I just told him today, 'You're the love of my life,'" revealed Jess.
"I don't really ever say that to anybody."
We wonder how Tony feels about his not-so-secret nickname.
