Speaking candidly on his girlfriend's mum Kris Jenner's talk show, Kris, set to air on Friday, the rapper opened up on his relationship with the TV reality star.
"I could have people saying, you know, this is going to damage your credibility as an artist or as a designer and I say, you know, 'I don't care, I love this woman.'"
In the preview of the show, the new dad went on to explain the doubts people may have about their relationship: "Everyone knows you don't like paparazzi, why would you be with this person?"
He answered the question himself: "I'm being with this person because I love this person and she's worth it to me."
The notoriously private rapper – who is expected to share the much-awaited first photo of his two-month-old daughter North West – also addressed the recent death of his grandfather, Portwood Williams Sr., who died earlier this month at the age of 98.
"You know my grandfather just past and (for him) it was never about money, it was never about popularity, his whole thing was joy, just joy, having joy in his life," said Kanye to a huge round of applause from the audience.
"She's my joy," said the rapper, referring to Kim, "and she brought my new joy into the world and there's no paparazzi and there's no blog comment that's gonna take that joy from me."
The show's host Kris, understandably touched by hearing Kanye's heartfelt words about her own daughter, reacted by saying to the audience, "That's pretty amazing."
Kanye, 36, has shown how eager he is to support his girlfriend's family by appearing on the chat show. He is also expected to share a family snap of his little one – the first to be seen in the public eye.
Friday's episode of Kris is the last of a six-week trial.
