Pharrell Williams and designer Helen Lasichanh have been together for more than a decade - but they were purely friends to start. "She just stood out. I was like, 'Who and what is that?'" the "Happy" crooner recalled during an interview in April 2014. "I knew at some point something was going to happen. I was just so enamored by the moment I was having with her. I just wanted to read that book. I didn't care what was in it." Williams added at the time: "She didn't answer half my text messages. She had a boyfriend and she wasn't interested." After more than two years of being platonic pals, Lasichanh eventually saw a romantic spark in Williams. Amid their whirlwind romance, their brood got larger when son Rocket was born in November 2008. Three years later, Williams popped the question. Us Weekly confirmed in October 2013 that they tied the knot. "Usher and Busta Rhymes did a mini concert at the wedding," a source exclusively revealed to Us at the time. "It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to. Of course, they're playing some of [Pharrell's] hits [too]."
