The musician made a public apology and gave a drunk-driving PSA as required in his plea agreement."So I don't, I don't know how many of you were in the courtroom and heard what I had to say in the courtroom, but I'll reiterate that and say this to you. Many of you have probably been covering me for a lot of my life. And as you may know, I try to hold myself to a very high standard for myself. And this was not that. I found myself in a position where I could have made a different decision, but I've had some time to reflect on that.""And I also understand by, you know, the fact that all of you are here, that I have a platform, you have a platform, we share that platform. And so what I like to say to everyone watching and listening, even if you've had one drink, don't get behind the wheel of a car. There's so many alternatives. Call a friend. Take an Uber.
