BEIJING, March 1 (Xinhuanet) -- American entertainer Marie Osmond's son jumped to his death Friday night from a downtown Los Angeles apartment building, according to media reports Monday.

The 18-year-old Michael Blosil is one of Osmond's five adopted children.

"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," Osmond said in a statement.

Blosil reportedly left a note which referred to a lifelong battle with depression.

In 2007, Osmond said Michael was treated at a rehabilitation facility, but she didn't disclose the nature of his problem.

Osmond is best known for the ABC variety show “Donny & Marie” in the late 1970s, in which she starred with her brother. She and her brother have also performed on ABC’s “Dancing With the Stars” and now have a variety show at the Flamingo Showroom in Las Vegas.
