Keri Hilson enjoyed working with Britney Spears.

"Britney, she's special," Keri explained. "She really isn't the puppet that people make her out to be. She has an opinion and she's a very, very bright girl. She's a pleasure to work with. You won't find any diva behavior in there."

"She's a very, very sweet person, takes direction very well," Hilson continued. "I can't say that she's guarded, but I understand why she doesn't want to talk about certain things, and I respect that about her."

Hilson is promoting her first solo album In A Perfect World, which will be released in September.
