R&B singer Ne-Yo has revealed that he's been a fan of 'Titanium' vocalist Sia for years and he's surprised that people are only just discovering her.

He praised her unique style and explained to MTV News that she deserves the recognition she is finally getting:

"For me personally, I've been a fan of Sia for a long time. From Zero 7 to Some People Have Real Problems, these are her albums and people that she worked with before she got popular, so to speak."

"She's been incredible for a long time. Her mastery of melody, from just the way that she works, her words and phrases, it's been incredible. And people are just now catching on! Y'all are late; everybody's late. It's been that way."

Other tracks that Sia enjoyed chart success with back in 2012 include Rihanna's 'Diamonds' and Flo Rida's 'Wild Ones'.

Meanwhile, Ne-Yo is working on Beyoncé's forthcoming new album although he recently confessed that he can't talk about it or give away any details about the project.
