The SexyBack singer and the prolific producer, who are longtime collaborators, have been working on Justin's forthcoming sixth studio album. On Tuesday, Timbaland, 51, took to Instagram to share two new posts involving Nelly, whom the producer worked with in 2006 to realise her Grammy-nominated album Loose. The first post included a photo of Timbaland and Justin, 42, in the studio on a FaceTime call with Nelly, captioned: "Da dream team @justintimberlake @nellyfurtado". The second was a snippet of Nelly's vocals playing out in the studio.
