"The plan was to shoot most of it around Tony's football schedule so she could support him through the season," a show staffer on The Price of Beauty -- which chronicles Simpson's worldwide search for true beauty -- tells Us.
"Now they're busy redoing the whole shooting schedule," continues the source. (It's still set to premiere on VH1 March 2010.)
The new issue of Us also reports Romo had been sending "flirty texts" to a younger, skinner Simpson look-alike, Natalie Smith, while still dating the singer. He even introduced Smith to Simpson at one of her February concerts.
"We hung out for, like 10 to 15 minutes, backstage," Smith tells Us. "She was cool and nice."
A Smith source tells Us Romo, 29, and Smith, 22, "are not officially dating, but they are having an intimate relationship."
Romo dumped Simpson on July 9, the eve of her 29th birthday.
Now, a sign hangs in the security booth of his Dallas gated community that 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."
Simpson spent $19,000 to ship 37 boxes of her belongings overnight to Los Angeles on July 15.
