State police spokesman David Procopio says Bundchen was going about 70 mph in a 55 mph zone on state Route 6 in Barnstable when she was stopped Saturday.
Procopio says two children were in the Cadillac SUV, properly fastened in car seats.
The trooper reminded Bundchen that the speed limit on Route 6 is 55, and let her go on her way.
Procopio says Bundchen did not get any special treatment. The same trooper gave four other drivers verbal warnings that afternoon. He gave 20 others written citations, but those drivers committed other violations in addition to speeding.
The stop was first reported by the Boston Herald.
