Will Smith got candid about his mental health journey, revealing that he once contemplated suicide.

The “Aladdin” actor shared the trailer for his upcoming YouTube docuseries titled “The Best Shape of My Life,” which follows Smith as he attempts to lose 20lbs in 20 weeks while finishing his first memoir.

“When I started this show I thought I was getting into the best shape of my life, physically,” Smith, 53, said.

“But, mentally, I was somewhere else,” he says in the trailer. “And I ended up discovering a whole lot of hidden things about myself.”

Smith added that writing his memoir felt like “exposing my life and so many things that people don’t know about me.”

The trailer then cuts to Smith sitting beside his family members – including his three children, Trey, 28, Jaden, 23, and Willow, 20, – as he reflected on previous suicidal thoughts.

“That was the only time in my life that I ever considered suicide,” Smith said. It’s unclear what specific period in his life Smith was referring to in the trailer.
