A tragically grainy photo circulating on the Internet (and first posted at GossipRocks.com) purports to present Lindsay Lohan going to third base on then-boyfriend Calum Best. What's more, the image allegedly is a frame grab from a cell phone-recorded video that Best took of Lohan in action (and unbeknownst to her).

While a source close to Lohan tells the New York Daily News' Rush & Malloy, "I think it's her," a rep for Best denies it's him on the receiving end. "Sorry to disappoint you," the flack tells Us, "but it's not Calum in the tape."
