Marie Osmond's son Michael Blosil took his own life Friday night after leaping to his death from his Los Angeles apartment, E! News confirms.

The 18-year-old reportedly suffered from severe depression in recent years, leaving behind a note which detailed his plans to commit suicide. In it, Blosil explained his loneliness, stating that he felt as if he had no friends and simply did not fit in.

Osmond expressed her grief over the tragedy in a statement released Saturday evening: "My family and I are devastated and in deep shock by the tragic loss of our dear Michael and ask that everyone respect our privacy during this difficult time."

An autopsy will likely be done Sunday.

Back in 2007, Blosil, then age 16, entered a rehab facility for undisclosed treatment. At the time, Osmond released a statement saying "Michael is an amazing young man, shown through his courage in facing his issues. As his mother, I couldn't be more proud of him."

Blosil is one of Osmond and her music producing ex-husband Brian Blosil's seven children, five of whom, including Michael, are adopted.

Prior to any public knowledge of Blosil's emotional issues, Marie fought back against National Enquirer claims that she herself had attempted suicide in 2006, and had been hospitalized in Utah.

Osmond and brother Donny have indefinitely canceled their Las Vegas show at the Flamingo Hotel.

Speaking to Entertainment Tonight on Saturday, Donny simply said, "Please pray for my sister and her family."
