Marie Osmond has denied her son committed suicide at 18 because he was gay, then added that if he was she wouldn't care.

In an appearance Thursday on the Oprah Winfrey Show, Osmond opened up for the first time about the loss of her son.

“My son was not gay,” Osmond said.

Osmond said Michael Blosil wanted to get married, travel and start a family.

“And it wouldn't matter if he was,” the 51-year-old Mormon mother added. “I have a daughter who is gay, and it was my daughter who was offended by it. 'What? All gay kids commit suicide?' She really wanted it cleared up.”

Rumors that Blosil was gay surfaced on the Internet after he jumped to his death in Los Angeles last February.

The freshman student at the Fashion Institute of Design and Merchandising in California first attempted to end his life in 2007 after his parents divorced. He is one of five children adopted by the couple.

Blosil battled substance abuse and depression much of life.

His suicide note “said he knew that morning that was the last time he would get up and brush his teeth, eat breakfast, make his bed – those kinds of things,” Osmond told Oprah. “And that he loved his family, but the pain was so intense.” (The video is embedded in the right panel of this page.)

Osmond has dedicated her new album I Can Do This to the memory of her son.
