BUSY PHILIPPS & MICHELLE WILLIAMS

Another duo whose fictional high school years (the two costarred in Dawson's Creek) blossomed into a lifelong friendship, the actresses keep up a bicoastal best-friendship that includes Philipps being godmother to Williams's daughter Matilda, 5. When Williams and Matilda visit L.A., they have playdates with Phillips and her girl, Birdie, 2; when Philipps visits N.Y.C., she and Williams sneak in some grown-up time, dressing in chic clothes for a party at Barneys.
