The superstar couple - who first started dating in 2016 and reconciled their romance earlier this year after splitting in 2017 - have found a ''balance'' despite their differences.
She explained to 'Entertainment Tonight': ''I think when you're attracted to someone, it's sort of like how opposites attract.
''I'm looking for that balance and maybe he's looking for [someone who is] a multi-tasker.''
The 33-year-old singer admitted her 41-year-old boyfriend has been trying to get her to join him in some of his healthy new habits.
She joked: ''Ugh! He's always trying to get [me] to go hike, or do yoga or eat vegan.''
When her fellow 'American Idol' judge Luke Bryan teased his co-star would rather hike to Taco Bell, Katy seemed to agree.
She laughed: ''I sure will! Crunchwrap supreme, extra meat, extra onions.''
Her comments follow reports that the 'Pirates of the Caribbean' star is feeling ''very happy'' in his relationship with the 'Part of Me' hitmaker and is feeling ''like a new person'' as he's ''matured'' a lot since the first time they started dating.
The insider told PEOPLE.com: ''He is ready to settle down with Katy.
''Being with Katy makes Orlando very happy.
''In the past, he seemed so scattered and unwilling to settle down. He is like a new person now and everyone is excited for him.''
They added: ''Orlando is in a different place than he was last year.
''He has matured a lot. He realised that being single isn't that great after all. His relationship with Katy wasn't right the first time around, but it very much is now.''
