The 35-year-old rapper is dating Kim Kardashian and loves spending time with her clan as he misses being part of a family ever since his mother, Donda West, died from complications after plastic surgery in 2007.
A source told HollywoodLife.com: "I know he misses his mother and wishes she were here with him, so now he's connected with the Kardashian family and it's perfect for him. He likes being around all of them and they like him, so he is already family. He ain't even got to get engaged and married - he's already married and don't even know it."
While Kim and Kanye have only been dating for eight months, the pair are reportedly planning a wedding even though she is still married to basketball player Kris Humphries.
Kim previously said her next wedding would be very different to her multi-million nuptials with estranged husband Kris.
She said: "It had always been my dream to have a big wedding, and when people said I'd made it over the top for the show, that was just me: I am over the top. But the next time, I want to do it on an island with just my friends and family and that's it."
