John Mayer is ready to move on, after being super candid in interviews about his sex life and exes, Jennifer Aniston and Jessica Simpson back in 2010.

The singer/songwriter sat down with Ellen DeGeneres for a now-rare interview airing Tuesday and revealed he has learned from his mistakes and won’t be opening his stupid mouth again.

“It was a very strange time and it sort of rocketed me into adulthood. It was a violent crash into being an adult,” Mayer told DeGeneres. “For a couple of years, it was just figuring it all out, and I’m glad I actually stayed out of the spotlight… It was like, ‘No, idiot. Go away and be 33 and 34 instead of 28 for the fourth year.'”

With a new album on the horizon, Mayer is also dealing with some lingering vocal-cord issues. Will he ever be able to sing again?

The “Shadow Days” singer — whose new album, Born and Raised, will be released May 22 — revealed medical issues have caused him to cancel his spring tour and scale back on album promotion.

“They cut this thing out of your throat and then they inject your vocal cords with Botox, which freezes your vocal cords so that this thing can heal without smacking up against the other side. I just need more Botox next time,” he explained. “It’s not a health concern whatsoever, but it has taken me out of singing. I tried to beat it the first time and couldn’t.”
