Indie film powerhouse Christine Vachon is turning 46. Bjork is 43. Goldie Hawn is 63. Publicist Mara Buxbaum is 41. Retired football player Michael Strahan is celebrating his 37th. Actress Cherry Jones is 52. Real estate developer Daniel Brodsky is 44. Norman Siegel, civil rights lawyer and perennial candidate for public office, is 65. Congresswoman Yvette Clark is 44. Nicollette Sheridan is 45. And actress Marlo Thomas is 71. Weekend birthdays after the jump.
