Jada Pinkett Smith Says She Was Addicted to Porn Before Meeting Will Smith

Jada Pinkett Smith is coming clean about one of her past addictions ... she says she couldn't stop watching PORN before starting a relationship with Will Smith.

Jada made the stunning revelation in Monday's "Red Table Talk" episode ... opening up about her "unhealthy relationship" with porn and saying she couldn't get enough adult videos when she was single and trying to practice abstinence.

The 47-year-old actress started talking porn with her daughter, Willow, and mother, Adrienne Banfield Norris, at the start of the show as they were all getting ready together backstage ... gotta be an awkward convo for any family.

Willow asks her momma if her porn fixation came from an emotional place ... and Jada says that's exactly what happened. Jada, who's been married to Will for almost 22 years, says she was feeling an emptiness when she got hooked on porn.

Monday's talk was about the effects of porn on relationships ... and Jada says she used to watch some hardcore videos she says were "profoundly disturbed."
