I love keeping secrets. That [last] one is gonna rock some boats."

Despite revealing her surprise duet, the Young Money star refused to say when her next LP will be released, adding: "I can give you an idea, but I don't want to. I'd rather not right now. Because then everybody is gonna jump on the bandwagon and say they're putting out their album the same day."
