Will Smith says Jada Pinkett Smith 'cried for 45 days straight' when he was 'failing miserably' in their marriage

Will Smith has spoken candidly about his wife Jada Pinkett Smith's struggles through their marriage.

In a clip from an upcoming episode of Red Table Talk, the 50-year-old actor joined his wife, their 17-year-old daughter Willow Smith and his mother-in-law, Adrienne Banfield-Jones.

"There was a period where Mommy woke up and cried for 45 days straight. I started keeping a diary," Will told Willow, before Jada, 47, said with a laugh, "You missed some days."

"It was every morning," said Will. "I think that's the worst I've ever felt in our marriage. I was failing miserably."

Red Table Talk is a web series hosted by Jada, her mother and her daughter. The three women often delve into personal and sometimes dark subjects including sex, mental health, relationships, loss and more.

In a previous episode, Jada said she's dealt with various addictions her whole life including sex, exercise and alcohol.

"I was in the house by myself and I had those two bottles of wine and was going for the third bottle," she recalled in one anecdote. "And I was like, 'Now hold up. You're in the this house by yourself going onto your third bottle of wine? You might have a problem.'"

Jada has also opened up about mental health and self care -- most recently after the sudden deaths of Anthony Bourdain and Kate Spade four months ago.

She took to Instagram to talk about her own experiences.

"In the years I spent towards my healing, many moons ago, I realized the mind and heart can be extremely delicate without the foundation of a formidable spirit," she wrote. "What I eat, what I watch on TV, what music I listen to, how I care for my body, my spiritual practice, what people I surround myself with, the amount of stress I allow and so on... either contribute to or deteriorate my mental health.

"Mental health is a daily practice for me," she continued. "It's a practice of deep self-love. May Kate and Anthony Rest In Peace. Many may not understand... but I do, and this morning I have the deepest gratitude that I pulled through."
