Amber, 32, and Blac, 28, had an honest chat, and dropped a few bombshells with expectant mother-of-one Blac admitting her fiancé Rob Kardashian was unimpressed with some of her antics.
Speaking about the use of sex toys, the video vixen revealed: 'Rob doesn't like it. I got to kind of sneak it sometimes. I wait until he leaves.'
And Amber admitted she already knows everything about Blac, joking: 'I know every guy that Chyna has ever slept with"
But despite being liberal-minded, Amber also admitted she has gone a year without sex.
'If I'm not in a relationship - like I'm not in a relationship now - I don't feel the need to go out and find someone to have sex with. I don't feel an urge.'
Meanwhile Blac Chyna revealed she feels more educated with the baby she is expecting with her fiancé Rob, having previously given birth to three-year-old son son King Cairo, the child she shares Tyga.
With her new-found knowledge, the pretty star hinted she is considering eating her placenta following the arrival of her daughter - by utilising the growing trend of having the placental sack frozen and put into edible capsules.
'Just recently I found out some new, cool stuff about not cutting the cord and sending your placenta.
'You can get these pills to take them after to make you and the baby healthy. If you notice dogs and cats, when they have their babies, they eat the placenta.'
