On 26 July 2020, Villegas' 22-month-old daughter Mía died after battling tumours on her brain and spine. Following her death, the PGA Tour paid tribute to her in the following tournaments, including the PGA Championship, and the Wyndham Championship, by giving players some small rainbow pins for their caps, as Camilo revealed Mia's immense love for rainbows. Many players continued wearing the pins in their caps for the rest of the season, and Villegas received immense support within the PGA community, the sporting world, and his fans in Colombia.
