Notoriously private star Janet Jackson is set to lift the lid on her life in her new documentary, named Janet, which is due to come out on January 28.
Janet, 55, will discuss her late brother Michael Jackson in the film and it has now been reported that Justin Timberlake will make an appearance.
The former N*Sync singer, 40, taking part suggests that the documentary will discuss the duo's 2004 Super Bowl halftime show performance and the controversy surrounding their performance when Janet's breast was exposed by Justin.
