Kirsten Dunst has vehemently denied she is romancing Orlando Bloom. The stunning actress was linked with the handsome actor when they were spotted looking close on the set of new movie Elizabethtown. But Kirsten, who is dating Donnie Darko star Jake Gyllenhaal, insists the pair are just friends. Speaking at the Venice Film Festival, she said: 'If you're alluding to whether Orlando and I got together then that's a no. No.' However, Kirsten admits she understands why co-stars do fall for each other. She said: 'There are a lot of charismatic people in this industry so I understand why people on location get together.' Kirsten and Jake, who recently denied wedding rumours, were reported to have split last year. But it was later revealed the pair had concocted stories of a break-up to take the heat off their relationship. The Hollywood couple started dating after being introduced by Jake's actress sister, Maggie Gyllenhaal, who co-starred with Kirsten in Mona Lisa Smile.
