Grayson Arroyo-Smiley, the son of Slade Smiley and step-son of former The Real Housewives of Orange County cast member Gretchen Rossi, alongside mother Michelle Arroyo, passed away after battling a rare brain tumor since 2006. Grayson was first diagnosed just days after his 6th birthday. He then went on to spend the remainder of his years battling against a rare, invasive, and slow-growing tumor called Diffuse Fibrillary Astrocytoma.
