Pepsi and Viagra: Yes. NutriSystem: No.

Former Sen. Bob Dole may have endorsed a soft drink and a prescription drug, but he and his wife Elizabeth are not hawking a diet plan.

Mrs. Dole, a former North Carolina senator, mentioned at a lecture Sunday that the couple was going on the NutriSystem diet plan, which has had former NFL coach Don Shula and Go-Go's lead singer Belinda Carlisle as celebrity spokespeople.

But a representative of NutriSystem said the Doles are not getting paid.

"NutriSystem doesn't have any plans to sign them up as spokespeople, but we're thrilled that they're going on the program," spokeswoman Regan Preston told Dome.
