Kellie Frost is known for being the widow of the late Lane Frost, a legendary bull rider who died in a bull riding accident at the Cheyenne Frontier Days in 1989. Several years after Lane's passing, Kellie married Mike Macy, who is also a rodeo competitor.
As of 2016, neither Kellie nor Mike are active in rodeo. However, both of their children, 20-year old Aaron and 17-year old Brogan, were accomplished junior rodeo competitors, and Aaron is currently a roper for Weatherford College. Kellie and Mike live on the family's ranch in West Texas, where they raise bulls and cattle.
