Kirsten Dunst Denies Justin Long Romance 9/11/08

Latest: Kirsten Dunst has laughed off speculation she is romancing Justin Long, insisting the rumors "are the funniest thing on planet Earth".

The Spider-Man star has been repeatedly photographed with Long over the summer (08) shortly after he announced his split from actress Drew Barrymore in July.

But Dunst insists she is currently single - and has only met Long once.

She says, "I don't know him from Adam. I met him once and he and his friend were kind enough to walk me home. I've never seen him since."
