Shields and Cruise had a public beef last year after the "Mission: Impossible III" star criticized the actress for taking antidepressants after the birth of daughter Rowan, who turns 3 this month. Rowan was her first child with TV producer-husband Chris Henchy.
"You know, the irony is perfect," Shields tells newsmagazine "Access Hollywood" in an interview that was to air Monday night. "The world works in an interesting way, but we (were) both pretty busy that day."
Both children were born April 18, reportedly in the same Los Angeles hospital. "Yeah, rumor has it," says Shields, 40. "Again, I was pretty distracted."
When asked if she had any run-ins with Cruise at the hospital, she replied: "No. God, no, and it's a gift having kids, you know, so it's a beautiful thing rather than anything else."
Cruise, echoing the position of Scientology, said in an appearance on NBC's "Today" show that depression can be treated with exercise and vitamins rather than drugs.
Shields, who wrote "Down Came the Rain: My Journey Through Postpartum Depression," has dismissed the actor's remarks as a "ridiculous rant" and "a disservice to mothers everywhere."
"I'm going to take a wild guess and say that Mr. Cruise has never suffered from postpartum depression," she wrote in an op-ed piece in The New York Times last July.
