Watch Meghan Trainor Sing Her Hits (and Meet Her Idol Dr. Phil!) in New Carpool Karaoke
"I worship Dr. Phil," the singer-songwriter says. "I went to his show the other day and I couldn’t stop crying"
Apparently, Trainor really loves Phillip C. McGraw, a.k.a. Dr. Phil. “I worship Dr. Phil,” she says. “I went to his show the other day and I couldn’t stop crying.” So, Corden arranged for her idol to surprise them by hopping in the backseat. “Your teeth look so good. So handsome,” she exclaims.
Dr. Phil then gives Trainor a free 1:1 session, which she chose to use to talk about her struggles with panic and anxiety. “When you talk about it, it gives it a face, it gives it a voice,” Dr. Phil says of breaking the stigma surrounding anxiety. They then sang “All About That Bass” together, which pushed Trainor over the edge of excitement.
