Darlene Egelhoff, reality TV star Heidi Montag’s mother, had a terrifying mountain bike accident while on vacation in Utah.

Egelhoff – who remains estranged from her famous daughter – was biking off-road with husband Tim Egelhoff when she lost control and plunged down a steep rock face.

Later, she twittered: “Near death experience on super steep slick rock in Moab! Rolled a couple times, stopped on the edge of a cliff! Scrapes& bruises PRAISE GOD!”
