Star sends touching message to Kanye West on Mother's Day

Kanye West may have lost his biological mother seven years ago to a cosmetic surgery accident, but his mother-in-law, Kris Jenner is doing all she can to fill that void.

The Kardashian matriarch offered some comfort to her 37-year-old son-in-law on Sunday, May 10 posting a throwback photo of the two on her Instagram and promising to stick by his side.

Kris, 59, wrote: ''And of course I'm thankful for this love bug #KanyeWest who has been a constant in our lives and showered us with unconditional love, support, kindness, friendship, and lots and lots more love. I learn something new from him every single day.''

''I will never replace his beloved Mom Donda but I will always be here for him and love him like my own son. #blessed #grateful #mothersday,'' Kris adds, showing just how much Kanye means to her.
