If there was the slightest shred of doubt that Tony Romo & Jessica Simpson are just havinga fling- it just flew out the window.

The Dallas Cowboys quarterback made a bold move last night, bringing the “With You” singer along for the ride on a radio interview with Live 105.3 FM’s show “Inside the Huddle.”

Kid sister Ashlee Simpson tagged along, joined by her boyfriend Pete Wentz.  And the celebrity posse created quite a stir among the show’s few hundred spectators, to the point that they got started late due to immense demand for autographs and pictures.

Clearly, Romo was making the point that Dallas fans need to buck up and accept his relationship with Jessica (if you haven’t been paying attention, some Cowboys fans are rising up against the relationship, claiming Tony is playing poorly as a result).

I’ve got $20 that they don’t make it to the New Year.
