Chris Rock and his wife, Malaak, looked like the happiest of couples yesterday on "Oprah," where they promoted his new comedy, "I Think I Love My Wife." But some claim the movie - in which he stars as a husband tempted by foxy Kerry Washington - is closer to real life than Chris would like to admit.


Speculation about Rock's 10-year marriage has heated up since Washington called off her engagement to actor David Moscow.


Washington tells us Rock had nothing to do with that split, and Chris' rep maintains, "Everything is fine at home for the Rocks."


But the Rocks have known their struggles. In November, TMZ.com reported that Chris hired a "high-powered" attorney to begin "divorce proceedings," and a friend of Chris' confirmed the couple were talking to lawyers. Word was they were trying to work out a post-nuptial agreement.


Now the producers of "I Think I Love My Wife" are said to have urged Chris to postpone any decisions until after the movie's March 17 release. "They read him the riot act," says a source.


Malaak's friends say she complains that Chris doesn't offer enough support in her charitable work. Others say Malaak worries about his time away from home. About five years ago, L.A.-based model Monika Zsibrita pressed a paternity claim against Chris. (Three DNA tests established he wasn't the father of Zsibrita's child.) Rock's rep says that his relationship with Zsibrita took place while he and Malaak were separated. Last year, Rock joked onstage, "I don't cheat. Not because I'm a great husband, just because I'm tired of getting caught."


Whatever their past troubles, Malaak says Chris has turned into a great father to their two daughters, 4-year-old Lola and 2-year-old Zahra. As Rock told Oprah: "Taking care of my kids is what I really want to do."
