Kanye West became addicted to opioids after having liposuction.
The 'Bound 2' hitmaker underwent the procedure in 2016 because he didn't want people to call him "fat" like they did to Rob Kardashian.
Speaking on TMZ Live, he said: "I had plastic surgery because I was trying to look good for y'all. I got liposuction because I didn't want y'all to call me fat like you called Rob at the wedding and made him fly home before me and Kim got married.
"I didn't want y'all to call me fat, so I got liposuction. They gave me opioids and I started taking two of them. And then driving to work on the opioids."
And the 40-year-old rapper - who has North, four, Saint, two, and Chicago, three months, with his wife Kim Kardashian West - previously admitted that he uses the "world" as his therapist.
He explained: "I use the world as my therapist. Anyone I talk to I talk to is my therapist. I will pull them into the conversation when I'm feeling at that point and get their perspective. Sometimes they'll be like, 'Damn, I'm talking to Ye, I'm not expecting to talk about this.' I use that. I talk through things. Anybody that I'm around, and I'll put that as advice to people.
Use people around you as your therapist. Because they probably know more about you. A therapist does a crash course in Ye and then comes and is like, 'I'm gonna give you some advice.' I'm not saying that therapists are bad, I'm just saying that I like just talking to acquaintances, friends, family, you know, and I'll keep 'em on the phone, you know, for 45 minutes at a time, talking through things. It's kind of narcissistic."
