News of Beyonce releasing her fifth studio album in 2013 has left fans wondering what will it sound like? One of Bey's longtime collaborators Ne-Yo recorded a few songs with her but he's apparently staying mum about the top-secret project.

"I can't say what kind of vibe. I've been sworn to secrecy," he tells MTV News, adding that he doesn't want to upset Beyonce's famous other half. "Jay-Z is not a person you want mad at you! I got to be quiet!"

The global pop star's forthcoming effort will mark her first release since giving birth to her beautiful daughter Blue Ivy. When Ne-Yo was asked if motherhood had changed the way the 'Irreplaceable' singer works in the studio, he simply said, "No."

"She's had the exact same drive that she's always had," he explains. "She's not a person that slacks off in the studio. I mean it's not like slave labor or nothing like that, she's not cracking the whip. But it's definitely 'Let's get the job done, let's get the best song possible produced or written out of this experience.' And it's the exact same thing now."

As for Ne-Yo, his plans for 2013 include a healthier lifestyle. The 'Let Me Love You' crooner revealed that one of his New Year's resolution is to eat healthy. So guess what? He is going vegan.

"What's everybody's New Year's resolution? I'm going to try to go vegan," he tweeted to his followers. "Discipline test. Not looking forward to it wish me luck!"

Good luck! We wish Ne-Yo stays healthy and creative in 2013.
