Welch expressed relief at not becoming Swift's mother-in-law, despite clarifying she holds no ill will towards Swift.
She highlighted the irony that while she was unable to discuss the relationship, Swift released an entire album, The Tortured Poets Department, widely interpreted to be about Healy.
Welch confirmed that Healy has taken the situation "in completely good grace" and is now engaged to model Gabbriette.
Healy himself remained tight-lipped when asked about the album, stating he hadn't listened much but presumed it was good.
