Pete Davidson has always had his mom in his corner, especially through the ups and downs of his sobriety journey. "She's been the most supportive ever," he said on the Tuesday, September 23, episode of the "This Past Weekend With Theo Von" podcast. "It got to a point where she called me when I was in rehab and she was like, 'My biggest fear is that I will turn on the news and see that my son has died.'" Davidson, 31, has long been open about his struggles with mental health and addiction.
