British pop star Cheryl Cole has revealed a passion for murder documentaries and television shows dealing with the use of forensic evidence.

Cole, 28, has apparently been unwell of late, giving her time to follow the American series, "The First 48", which features police investigations into homicides.

According to Now magazine, Cole tweeted: "It's after midnight so hopefully the kiddies will be in bed. Does any(body) watch The First 48 on the crime channel? It fascinates me."

It seems Cole's fans are also avid viewers; one fan replied: "It seems quite scar(y)."
