Chrissy Teigen credits Carl Radke with lighting a fire in her to get sober again after she returned to drinking. "I am grateful to @carlradke. Not for just all the years on Bravo he has blessed us with, but because of his honesty and openness around his own journey with sobriety," Teigen, 40, wrote via Instagram on Tuesday, January 27, applauding the Summer House star, 41, for talking about his sobriety with her on a recent episode of her "Self-Conscious" podcast.
