Monica Culpepper is breaking her silence on the tragic death of her eldest son, Rex Culpepper, at the age of 28. "No words. Feeble try..." the Survivor alum, 55, wrote via Instagram on Monday, April 6. "Our world stopped at 5:12 pm on 3/14/26. We are overwhelmed with a gut wrenching grief, so hard it makes us ill. It's as if the world is spinning and we are stuck somewhere detached. The nausea is constant. Our worst nightmare won't end." Monica said it's been an incredibly difficult time for her family while expressing gratitude to the fans who sent well-wishes.
