CSI: CRIME SCENE INVESTIGATION star Marg Helgenberger is desperate for the chance to act opposite a romantic leading man, instead of a forensic cotton swab sample.

The actress has been begging producers to write in a love interest for her character, Catherine Willows, but her pleas have fallen on deaf ears.

She explains, "I keep telling the producers I'd love to have a relationship. We do a lot of cerebral work on the show playing opposite a swab or a computer screen.

"It would be great because it would give my character the opportunity to show a few more colours - her passionate side, or intimate side or vulnerable side."

Helgenberger even has the perfect leading man in mind for the role of her love interest - GARY DOURDAN - who plays CSI investigator Warrick Brown on the show.

She adds, "I'd much rather play opposite someone like Gary Dourdan - he's not bad at all!"
