Heidi Montag and Spencer Pratt Gobble Up Tacos, Publicity

If it seems as if we've used the headline above before, well, that's because we have. A year ago. But here Spencer Pratt and Heidi Montag are again.

We're not sure what makes us want to hurl more, food from Taco Bell or The Hills stars feeding each other food from Taco Bell. We'll call it a toss-up.

The quasi-celebrities were handing out this gourmet cuisine at the annual "Reality Check Challenge" for Global Hunger at the Bell in L.A. on Thursday.

THG NOTE: You may want to keep a paper bag handy as you view the image below. It's not for the faint of heart. Or those who ate in the last hour.

Heidi Montag glances seductively at Spencer Pratt's ... taco.
