My kids think Pharrell is my boyfriend: Gwen Stefani

Singer Gwen Stefani might be married to Gavin Rossdale, but their sons think their mother has fallen for Pharrell Williams.

She joked on the red carpet at Sunday's Grammy Awards about what her children think of her relationship with Williams, reports people.com.

"They were such a huge fan and I was like, 'Actually, I know Pharrell. I started showing them pictures on the internet and they were like, 'Wait a minute, is he your boyfriend?' I'm like, 'No.'" said Stefani.

But Zuma, 6, and Kingston, 8, aren't the only ones in awe of "The Voice" judges' relationship.

The music producer's 6-year-old son Rocket has been spending his time catching up on Stefani's classic tracks.

"It's interesting because now Pharrell's little boy has discovered my music and it's flipped," she said.
