It looks as if things may be over between Katy Perry and John Mayer. A source has confirmed to "People" that the couple has called it quits after seven months of dating. Katy and John started making headlines last summer, less than a year after Katy's divorce from Russell Brand. The relationship appeared to be getting serious last December when the two spent Christmas together. They've made a number of appearances as a couple at some high profile events this year as well, including the Presidential Inauguration and the Grammys.
It's not the first time breakup rumors have followed Katy and John. Their split was reported prematurely back in August. Last month, it appeared that Mayer, who has a reputation as a serial celebrity dater, could have been changing his ways for Katy. On "CBS Sunday Morning," he called the relationship "very human" and said he could see himself getting married someday.
