ALERT: ET Visits The Set of 'Weeping Willows'

Entertainment Tonight will be visiting the set of CSI's "Weeping Willows" to get a sneak peak at the episode from the show's stars.

In "Weeping Willows", trouble brews for Catherine as the primary suspect in a murder investigation turns out to be a man she met at a bar earlier that night. Tensions flare between her and Grissom when she leaves out that detail when the pair begins to work the case. "This particular episode, the idea of it, came from me," Marg Helgenberger (Catherine Willows) told ET. "I sort of wanted to do something that turned into a sexual obsession, Looking for Mr. Goodbar."

Catherine's new beau will be played by none other than Alan Rosenberg, Marg's real-life husband. Rosenberg revealed filming the kissing scenes with his wife wasn't as easy as they made it look. "For me it is very unnatural," he admitted. "People cast husbands and wives and think it brings something extra to the table, that there will be an automatic intimacy there, but we have been together for 18 years. I find it very difficult to be intimate with my wife in front of a room full of people."

The couple met on the set of Ryan's Hope, the 70s soap opera both actors stared in. Romance, however, didn't come instantly for the couple. "Marg was so sweet, and we sat down between scenes and we just kept on talking and talking. And it was fantastic," Rosenberg remembered. "And twelve years later I got divorced, and moved out of the home, and we were lucky enough, I was lucky enough to run into her in a bank in West Hollywood. And she remembered me, to my amazement."

Visit the official ET Online website for a sneak peak at tonight's full segment and local listings guide. "Weeping Willows" will air tonight at 9/8c.
