Washington, Sept 24 : Justin Timberlake and dance duo Chase and Status are working with Rihanna on her new album and say the upcoming record will be more "grown-up".

Timberlake had earlier written and provided background vocals for Rihanna’s single ''Rehab''.

Contactmusic quoted him as saying: "The stuff we''ve come up with in the studio, it''s the next step for her. It''s a little more grown-up. It''s got some edge to it."

Rihanna is also collaborating with Chase and Status for the album and the duo love working with her.

Chase said: "When she doesn''t like something she''ll let you know. When she likes something she''ll let you know as well. If she''s not into the vibe she''ll be like, ''Nope, I don''t think it''s for me.'' Or if something is a bit too bolshy, she''s like, ''That''s not what I''m trying to push right now.''

"We just spent a lot of time with the writers and with her and she''s just a really cool girl, down to earth." (ANI)
