After 18 successful years of marriage to each other, and with failed marriages in both their pasts, Trisha Yearwood and Garth Brooks have a wealth of experience to share – and “Good Morning America” host Robin Roberts was the recipient.

Roberts is about to wed her partner Amber, so the country duo sent a video clip that didn’t go as smoothly as one would hope. Trisha started: “We’ve been asked to tell you what we think the secret of a happy marriage is, because we’ve been at it for almost 18 years.” After a few seconds of silence, she asked Garth if he’s going to chime in with his advice. “Are you gonna go?” Yearwood asks, to which her husband replied, “I thought you were.” It devolved from there.

Finally Garth imparted some real advice: “Never go to bed mad at each other,” he said, to which Trisha responded, “What, did you Google that?” The eventually did give Robin some advice that everyone can agree on – “Marry your best friend.”
