New reports suggest Charlie Sheen has HIV, but he is now stating it is undetectable in his system.

According to TMZ, sources said Sheen had known for more than two years that he was HIV positive.

They said he was taking medication and has had a series of blood tests, and over time the virus has become "undetectable".

Doctors say until medicine advances, once someone gets HIV they have it for life.

Sheen has freely admitted he's had scores of sexual partners, many of whom he was engaged with after being diagnosed.

Sheen is set to do a tell-all interview with Matt Lauer on the Today show in the US on Tuesday (early Wednesday NZ time).
