Grammys 2013: Cool tune, The-Dream, but what about that hat? The-Dream's "Boyz N the Hood" hat was the focus of much attention backstage at the Grammys on Sunday in Los Angeles. Allen J. Schaben / Los Angeles Times February 10, 2013, 9:03 p.m. Of the many fashion moments that had backstage buzzing -- Kelly Rowland and Jennifer Lopez's flesh-baring, Dr. John's kooky costume, Carrie Underwood's projection-flashing gown -- it was a hat that got the most chatter backstage, and online. When winning for rap/sung collaboration for "No Church in the Wild," from Kanye West and Jay-Z's "Watch the Throne," Frank Ocean and The-Dream offered typical awards show thank-yous. But Jay-Z, who was collecting his 17th trophy, wanted only to thank producer The-Dream's choice of ballcap. "I would like to thank the swap meet for his hat," the rapper joked about the "Boyz N the Hood" cap that looked inspired by the Slauson Swap Meet. Backstage, The-Dream wasn't talking about producing for Beyoncé or Rihanna (though he was quizzed about his work with Ocean and his own album). The burning question was where did he find that hat. Everybody's asking. He likes to make fun of me," The-Dream told reporters before revealing that he got the cap at mall retailer Spencer's. [It's] a really bad store for the young people.
