So we all agree that Beyonce's "Single Ladies" was the hottest song and video of 2009--right Kanye? The story behind how the massive hit came together is equally intriguing. Singer-Songwriter The-Dream and producer Christopher "Tricky" Stewart spoke to People about recording it after Beyonce (kinda) secretly wed Jay-Z in 2008. "It was the only public statement that they ever made about marriage," said Tricky. "When we went into the studio she didn't have a ring on or anything, because at that point they were still really hiding it. That's where Dream got that concept from."
