[Twitter co-founder Biz Stone]

A post on Adrants covering the Cannes Lions festival caught our eye this week. Specifically, when blogger Angela Natividad wrote, "This year was the first year Cannes recognized PR's role in getting a brand message across, so PR people just about creamed themselves getting here. Even Twitter's PR folk, Hill & Knowlton, couldn't help but say something smug about it before passing the mic to Biz Stone this afternoon."

Twitter? PR folk? Hill & Knowlton? This was all news to us so we did some investigating. Reached for comment, Twitter co-founder Biz Stone told PRNewser, "Hill and Knowlton invited me to speak at their session-Twitter has not hired them nor have we hired any PR company."

The session Stone speaks about was a Tweet Up hosted by Twitter and H&K at the festival. If anything H&K is trying to get the most out of the connection, and we can't blame them. An agency blog lists both company logos with the copy: "Joining forces at Cannes."
