Has Katy Perry moved on... to John Mayer?

Katy Perry And John Mayer Have A Sleep Over

It looks like John Mayer and Katy Perry might have a sure thing going — at least for now. After being spotted together on multiple occasions, it’s obvious that Mayer and Perry, two of top 40’s hottest artists are dating.

On Sunday morning John Mayer was seen driving out of Katy Perry’s garage after spending time together during a house party in Los Feliz, at Perry’s home the night before. Even though it looks like Mayer missed out on Katy’s wardrobe malfunction, it seems as though John has been otherwise attached at the hip to Perry.

This isn’t the first party Katy Perry and John Mayer attended as a couple. The two attended a Hollywood party thrown by big wig agent Michael Kives. An onlooker said of the couple’s behavior at the party, “Katy and John never left each other’s side and were flirting and affectionate the entire time. Katy loved it!”

It’s reported that since Mayer has met Katy Perry that he’s willing to hang his “womanizing” ways up and make big time changes. According to several sources, Mayer had a deep “heart to heart’ conversation with Katy after only a few weeks of dating, and he’s now certain that he’s ready to settle down for a serious relationship.

A source told RadarOnline.com: “John has had his eye on Katy for a while and he had to try and convince her that he was right for her. The best way he thought he could do that was by dispelling his past reputation as a Lothario to Katy,” the source continued. “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.”

Before Mayer, Katy Perry was married to comedian Russell Brand, with the divorce finalizing on July 16. After the split was announced she began casually dating Florence + The Machine’s guitarist Patrick Matera. Before Perry, John Mayer was dating a who’s who of Hollywood from Jennifer Love Hewitt, Jessica Simpson, Jennifer Aniston, and a rumored fling with much younger country star Taylor Swift.
