NICOLE & NAOMI

YEAR: 2007
Someone couldn't keep a secret. When BFFs Nicole Kidman and Naomi Watts went to the Oscars together that year, both women looked stunning. Watts, wearing a buttercup yellow Escada empire-waist gown, was keeping mum about being five months pregnant with her and Liev Schreiber's first baby. But in a major "oops" moment, the designer's rep had spilled the beans in a pre-show press release, causing lots of "is she or isn't she?" stares at Naomi's belly.
