The Grammy-Award winning singer poured his heart out to the Wide Awake star, confessing that he realized his womanizing ways made him look like a douchebag and that he is a different person now.
John, 34, wants to settle down, and in Katy, 27, he sees the perfect girlfriend.
“John has had his eye on Katy for a while and he had to try and convince her that he was right for her,” a source revealed.
“The best way he thought he could do that was by dispelling his past reputation as a lothario to Katy.
“He’s never been short of female attention in the past and has always been quick to milk that at every given opportunity.
“But John realizes now that it made him appear a bit of a douchebag and an unattractive catch.
“He knew he had to change his ways if he ever wanted to get serious with somebody and he had a heart to heart with Katy, telling her he was desperate to change his ways.
“Katy believed him and now their relationship is moving on. She wants to visit his home in Montana and has slowly warmed to the idea that he’s boyfriend material,” a source revealed.
As RadarOnline.com previously reported, Katy and John weren’t shy of showing their affection for one another at a friend’s pool party in the Hollywood Hills recently.
The happy couple was reportedly all over each other; he was looking down her bikini top and they were kissing passionately, like they “were on a honeymoon.”
John has been linked to string of beauties over the years including Jennifer Aniston, Jessica Simpson, Jennifer Love Hewitt and Cameron Diaz.
Katy’s divorce to comedian Russell Brand was finalized on July 16 – he filed legal papers in December 2011, after just a year of marriage, citing irreconcilable differences.
Brand himself has moved on from Katy and is now dating Dallas star Jordana Brewster’s sister, Isabella.
