Tony Romo has banned former girlfriend Jessica Simpson from entering the grounds his Dallas estate.

The Dallas Cowboys QB, who dropped Jess just a day shy of her 29th birthday last month, has instructed security staff to keep the notoriously-clingy Simpson out of his gated community.

Us Weekly writes: A sign at the entrance reads: “RED ALERT!!! TONY ROMO HAS MADE SOME CHANGES TO HIS LIST OF PEOPLE ALLOWED IN….JESSICA IS NO LONGER ON THE LIST AND NOT APPROVED FOR ACCESS.”

As you may recall, Jessica was accused of “stalking” ex John Mayer after their year-long romance ended in mid-2007.
