Ne-Yo has so many hats, he has to store them in three different houses.

The 32-year-old singer is known for his love of headwear, and though he has his favourites, he has "double-digit thousands" to choose from.

"I have a favourite style. I'm partial to a fedora, but I don't want to be a one-trick pony," Ne-Yo said.

"The last time I counted, I was up to the double-digit thousands. I can't even keep them all in one house.I have a bunch of them in my LA house, a bunch in the house in Atlanta and a bunch in storage space that just sit and wait on Daddy to come home."

The So Sick hitmaker shared his secrets for choosing the right hat.

"It's all about the way it fits my head. You can get two of the same hat and they're not going to fit the same - it's the way it sits on you."

Last year, Pharrell Williams became infamous for a Vivienne Westwood hat he donned at the Grammy Awards, but Ne-Yo insists he doesn't think that particular headwear would have been right for him.

Asked if he is annoyed that Pharrell stole his 'hat game', he told Heatmagazine: "I'm not. I feel like his hat game and mine are two totally different games. I don't feel like that specific hat would work for me.

"It's too big.Like, my head is already big. I don't need to amplify the largeness of it. It works ridiculously well for him," Ne-Yo said.
