The 'Eyes Wide Shut' stars started work on the follow-up to 2010's Outta This World last week and have stated that they want to collaborate with the Barbadian singer on the record.
"We've been trying to work with Rihanna forever! It's in the pipeline," JB told The Mirror.
"We were close to working with her on the last album and obviously it didn't work out. Hopefully it will work out this time."
Jason Derulo recently explained that he isn't going to work with JLS on their third album as he wants to "focus" on himself.
