After separating in December, CSI star Marg Helgenberger has officially filed for divorce from actor husband Alan Rosenberg. Helgenberger, 50, and Rosenberg, 58, have an 18-year-old son. The two met when they were both appearing on the soap opera Ryan’s Hope. Helgenberger cited irreconcilable differences as the reason behind her split from actor Alan Rosenberg, and is seeking spousal support while asking the court to deny him any. Helgenberger is perhaps best known for playing Catherine Willows on CBS’ highly rated drama, “CSI: Crime Scene Investigation. Rosenberg has guest-starred on his wife’s show, was a regular on the TV series “LA Law” and “The Guardian,” and received an Emmy nomination for a guest role on “ER.” Rosenberg has been under stress recently as president of the 120,000-member Screen Actors Guild, which is at an impasse in contract negotiations with the studios, with the possibility of a strike looming.
