He had a sobriety pact with Katy

In 2023, the 'Teenage Dream' singer revealed she hadn't touched alcohol in five weeks and was determined to stick to their three-month sobriety pact.

Appearing alongside her then-fellow 'American Idol' judges at a curated cocktail event at New York City's Mister Paradise, she said: "I've been sober for five weeks today… I've been doing a pact with my partner and I want to quit."

After Luke Bryan jokingly asked her if she would be giving in at the event, Katy replied: "No, girl! I can't cave. I made a promise. Three months."
