NEW YORK, July 1 (UPI) -- Producer Sean "The Pen" Garrett's collaboration with Britney Spears is "wowzers" and "out of control" -- just ask him.
The producer -- who is also working on songs for Usher, the Pussycat Dolls' Nicole Scherzinger, Keyshia Cole and Ashlee Simpson -- said has been holding the Spears record till it was perfect, Billboard.com reported Sunday.
"I've got this one record I've been holding for 10 months that everyone has tried to buy, but I stayed with Britney on it. I guarantee it will shake up the world," he said. "It's up-tempo, out of control ... it's wowzers, produced by me and Bloodshy. I can't give the title yet, but the record is done and definitely what people want to hear from her."
Garrett may have shared BMI songwriter of the year with Kara DioGuardi, but he said he still feels like he's at the learning stage.
"Winning songwriter of the year made me feel like, wow, I've accomplished something. But I'm not a person who feels he knows everything," he said. "Now I'm getting the opportunity to really start writing incredible records. And it's not about making money. I don't do it for that. I grew up loving music. This is my dream."
