They say you are what you eat, so it's no surprise failed Republican presidential candidate Rick Santorum loves him some anti-gay chicken.

The conservative 54-year-old just showed his support for controversial fast food chain Chick-fil-A -- whose president has been very vocal about the company's support for all things anti-gay lately -- by tweeting, "With two of my boys, Enjoying chick-in-strips and awesome peach shake at Chick-fil-A."

Then, in a reference to fellow GOP evangelical Christian Mike Huckabee's campaign for a Chick-fil-A Appreciation Day on August 1st, Santorum added, "See you here next Wednesday."

In response, pro-equality groups are coordinating a Same Sex Kiss Day at all Chick-fil-A restaurants on Friday, August 3rd. Now that's a mouthwatering meal.

Former presidential hopeful Rick Santorum did not take a photo WITH Lindsay Lohan last night -- but sources at the White House Correspondents' Dinner tell TMZ ... he took one OF her. 

According to our sources inside the party, LiLo was sitting with Fox News personality Greta Van Susteren when Santorum came up to say hello. We're told Lindsay was asked to take a picture of him with Greta using his camera, which she did. 

Then ... our sources say Rick asked to take a photo of Lindsay using his camera. Yes ... of just Lindsay.

We're told Lindsay smiled and obliged and Santorum then went on his way.

Our photog asked Rick about the picture after the party ... and he played dumb about the photo.

He might not be running for President any more, but he can't take any chances.
