Marie Osmond is opening up about her son Michael’s suicide at 18-years-old.

The star, 59, joined Global’s “The Talk” co-hosts Carrie Ann Inaba, Sheryl Underwood, Sharon Osbourne and Eve on Tuesday and got emotional in a rare interview about her son since his death in 2010.

“I have never spoken about this before. So, my son who died, he was bullied. He was bullied very heavily up until the time he committed suicide because of his sobriety,” she said. “I’ve got the texts. I mean they are horrendous and I never took action against it.”

Osmond added, “But, I can tell you, honestly, I believe that that was a big component in him just feeling overwhelmed and that he didn’t fit in. I never took action against the three kids. I know who they are. But maybe it’s not a bad idea to have some kind of consequence because it’s getting out of hand.”

Rumer Willis served as guest co-host on Tuesday’s episode and also opened up about the bullying she’s experienced.

“I got bullied very, very badly in school when I was younger, very badly,” Willis explained. “And I truly don’t know what would have happened to me if I grew up right now. The issue is systemic bullying, especially [on] social media.”

“The Talk” airs weekdays at 2 p.m. ET/PT on Global.
