I remember Masha posting on her website that she would miss Kim, I think it was in a doodle.
This is the exact quote:
Just heard that Kimmy is retiring! I wish her nothing but the best in her new chapter of life.She is truly a genuine person with a huge heart....not to mention someone with amazing accomplishments on the court.Sending you lot's og hugs Kim!!
