The actress made the remarks on the red carpet at the premiere of the film "Love Marriage Wedding."
Celebrities are weighing on the break-up of former California Gov. Arnold Schwarzenegger's 25-year marriage to Maria Shriver.
But "Dr. Quinn" actress Jane Seymour caused a stir when she remarked on a red carpet photo-op that she had heard Schwarzenegger fathered more than one child out of wedlock.
"From what I gather, I think there will be lots of information coming people's way," Seymour told a CNN reporter. "I heard about two more (out of wedlock children) somebody else knows about. I even met someone who knows him well."
Seymour made the comment at the red carpet premiere of "Love Marriage Wedding."
She also told the celebrity scribe, ""The moment I heard it, that there was an announcement of their separation - he was obviously jumping the gun before everyone else told the world of the news."
The 63-year-old Schwarzenegger admitted to Shriver that he had fathered a teenage love child with their housekeeper. Media outlets have identified the woman as Mildred Baena.
Shriver moved out of the couple's home a week before they announced the end of their marriage on May 9.
Since then, Schwarzenegger has kept a relatively low profile. He has delayed his Hollywood comeback as he braced for what could be a costly divorce.
Shriver has released a brief statement about the end of her marriage.
"This is a painful and heartbreaking time. As a mother, my concern is for the children. I ask for compassion, respect and privacy as my children and I try to rebuild our lives and heal. I will have no further comment."
