John Mayer has learned to keep his personal life private.
The 35-year-old singer - who has previously boasted about his romances with stars including Jennifer Aniston and Jessica Simpson - insists he won't be speaking about his recent split from Katy Perry after eight months of dating.
Asked about the end of their romance on Ellen Degeneres' show, which airs today (02.04.13), he said: ''It was a very private relationship going in. It was a private relationship during and it's a private relationship, still.
''I can understand asking the question based on some previous answers I have given but I have finally learned how to put the wall between one thing and the other.''
Despite his fame, John admitted he struggles with romance and says finding love is ''tricky''.
He added: ''I'm on the same journey as everyone else. Coupling is a tricky thing.''
Last year, the 'Gravity' hitmaker was forced to take a break from music after suffering from serious throat problems, and he admits he has now curbed his partying ways, particularly his love of whiskey, to help protect his voice.
He explained: '''Half of it is over use and singing and singing and singing. The other stuff is you know, what you put into your body. And, I'm getting to that age now your body doesn't just shake everything off and it didn't help that I really loved, love, loved scotch.
''It's just like applying poison to your body. It's like applying a shellac of poison. It's just delicious, wonderful poison that makes you not care how late you're out till or where you're going.
''But I had to really say I like singing and writing more than I like delicious scotch so I had to really dial it down. And, I'm a little more boring now.''
