Ricki Lake, whose Lifetime telefilm Matters of Life and Dating premiered Oct. 22, is busy promoting her new documentary,

The Business of Being Born. "It's about birth. It's about the politics of the medical system," Lake told TV Guide at Thursday (Oct. 25) night's Choose Your Cause (CYC): Launch Party and Charity Benefit at Fred Segal Santa Monica. "It raises a lot of questions about what is going on with birth today, with all the C-section rates and malpractice insurance and midwives. It looks at all of that from my own personal experience. It's fascinating." Lake's baby experience includes being mom to sons Milo, 10, and Owen, 6, (their father is Rob Sussman, Lake's husband - the couple are currently separated). The documentary opens in New York on Jan. 9, 2008. Lake may return to regular TV work, too, and says, "I did a pilot and it might get picked up, but I did it for last season but now they held my options. I don't know what's happening at ABC but it's called The Middle." - Reporting by Carita Rizzo
