STEALING BEAUTY: While in their new movie “Bride Wars,” Kate Hudson and Anne Hathaway play former best friends who scheme to steal each other’s “bridal thunder,” in real life the actresses are happy to complement one another. At the film’s premiere on Monday in New York, Hudson and Hathaway channeled a bride and groom in their red-carpet garb. Hudson wore a beaded and embroidered white Oscar de la Renta column along with mounds of Tiffany & Co. diamond jewelry, while Hathaway wore a modified black tuxedo from Band of Outsiders. “Kate had this idea in her head. She wanted to play off the whole bridal theme of the movie and do full-on and do something over the top. It had the drama of a bridal gown but it wasn’t totally bridal,” said Rachel Zoe, who styled both Hudson and Hathaway. “It was Annie’s idea to do a tuxedo and my initial reaction was that they were going to look like a bride and groom…and she liked that.”
