Jessica Simpson

Singer-actress Jessica Simpson and Dallas Cowboys quarterback Tony Romo are secretly married, Simpson's mother said, several reports said across the Internet. But Romo's agent denied that the quarterback was married.

Simpson was leaving a Chili's restaurant with her mother, Tina, on Tuesday when mama Simpson revealed the secret.

"Jessica is already married to Tony. What are you talking about?," Tina Simpson reportedly said.

Simpson told TMZ.com, "Well I guess if my mom said it, it must be true!"

She was previously married to Nick Lachey.

Romo's agent, R.J. Gonser, laughed at the report and denied Romo got married.

Romo, whose Cowboys lost in the first round of the NFL playoffs, said earlier this year that he was thinking about marrying Simpson.

"I'm sure I'll get married one day. I don't know when though," the 27-year-old said.
