Matty Healy's mom, Denise Welch, admitted she's "glad" she never became Taylor Swift's mother-in-law. Appearing on the Thursday, July 24, episode of Watch What Happens Live With Andy Cohen, the British TV personality, 67, took aim at the pop superstar. "Obviously on pain of death can I talk about that episode, but not being her mother-in-law is a role that I'm glad that I lost," she confessed after being asked what she thought of Swift's album The Tortured Poets Department, which is rumored to be inspired by Healy.
