Heidi Montag and Spencer Pratt took their nauseating roadshow to Taco Bell yesterday to help raise awareness in support of World Hunger Relief Movement and The World Food Programme.

The tacky twosome posed for photographers as they fed each other tacos in between serving up Taco Bell to the store’s customers.

At least one person was grateful for Speidi's presense.

Greg Creed, president, Taco Bell Corp said, “Heidi and Spencer have graciously helped with our inaugural program and we are fortunate to have them championing this cause for a second year.

"We are grateful and appreciate their efforts volunteering to feed those in need and helping raise awareness of the global hunger crisis,” Mr Creed added.

Speidi: Enough to put you off your tacos

Donations were being taken in amounts as little as $1 - with all proceeds raised in the U.S. going directly to The World Food Programme to help combat global hunger.
