Where Have They Been?: It's been a long six years for Justin Timberlake's fans since the release of his second album 'FutureSex/LoveSounds' way back in 2006, with Justin's last solo music release coming in 2007. The 'SexyBack' singer has focused more on his growing Hollywood career in recent years, with roles in hit films like The Social Network and In Time. When Will They Be Back?: While Justin has yet to announce his return to music the 'My Love' singer recently admitted recording is still a "special thing" for him, potentially hinting at a return to the microphone in the next few years.
