A weekend fire that destroyed a childhood home of Madonna has been deemed suspicious by arson investigators.

The Oakland County Sheriff's Arson Unit and the Rochester Hills Fire Department are investigating the Friday night blaze.

A passer-by had noticed flames coming out of the unoccupied house in the Detroit suburb of Rochester Hills and called the fire department.

Rochester Hills Fire Chief Ron Crowell told The Detroit News and Detroit Free Press the fire appears to have started in the living room area. He said it caused extensive smoke and fire damage throughout the two-story brick house.

The 49-year-old Madonna, known then as Madonna Louise Ciccone, spent some of her younger years as one of six siblings living in the home.
