Late Model Front Bumper Bolt stuck, Help!

[Silver Wagon]

anyone?!

[Silver Wagon]

so i started to pull out the 2 torx bolts that hold on my plastic bumper. one came out just fine. the other just spins. it unscrewed for a little bit, it was tough, but still turned. now its just spinning. i feel the captured nut in the bumper has broken loose and is spinning. how can i access that nut so i can get my bumper off?
drilling the head of the bolt won't work as its still captured by the bumper strut.

can i disassemble the plastic bumper while its still on the car?

please help, i want to get my new front valance on.
