Bryant opened up about the situation in his Showtime documentary "Muse" -- and while he never specifically mentions the case, it's crystal clear what he's talking about.
During the segment titled "2004" ... the year of the hearing (which was eventually dismissed when the accuser refused to testify) ... Kobe says:
"We were expecting ... and um ... expecting our second child during that time ... and there was just so much stress, she actually, she actually miscarried."
"It's something ... I have a real hard time dealing with that 'cause I felt like it was just my fault."
Kobe added, "The reality is it happened because of me ... that's something I have to deal with. Something I gotta carry forever."
Kobe also praises Vanessa ... saying she could have left him and taken half of his money ... but didn't.
