Rick Santorum reportedly asked Lindsay Lohan to pose for a photo at the White House Correspondents' Dinner on Saturday -- then denied it.

Lohan was sitting with Greta Van Susteren when Santorum approached, according to TMZ. He reportedly asked Lohan to take a picture of him with Van Susteren, then snapped a photo of Lohan alone.

Watch in the video above as a reporter asks Santorum if he took a picture of Lohan.

"I took a picture of a lot of people today," a visibly uncomfortable Santorum says, as though he cannot remember what happened. See a photo of Santorum leaning over Lohan's table here.

Santorum may have another chance to explain the encounter when he appears on "The Tonight Show" May 8.
