Demi Lovato is set to virtually sit down with Glenn Close for an honest conversation about mental health.

The pop star, who has been candid about her various personal struggles over the years, will be a guest on A Conversation Starter, a digital event for the Hollywood icon's Bring Change to Mind organisation, which encourages open dialogue about mental health to raise awareness, understanding, and empathy.

The discussion at 8pm EST on 23 May (21) will also feature U.S. newsman Anderson Cooper, who lost his brother Carter to suicide, as moderator, with a goal of encouraging attendees to either help themselves, support a loved one, or continue the dialogue within their own communities.

Lovato, Close, and Cooper will also answer questions submitted by the public to ensure audience participation.

Close founded Bring Change to Mind in 2010 after dealing with her sister's bipolar disorder and her nephew's schizoaffective disorder diagnosis.

Tickets for A Conversation Starter, which will benefit high school students involved in Bring Change to Mind's clubs across the U.S., are available here:
