John Mayer & Katy Perry's Romance: The 7-Month Itch?

Follow their relationship, from their summer of love to their post-Grammys separate lives

MONTH 2: SEPTEMBER

Though a source close to Perry told PEOPLE "she wasn't seeing forever with [Mayer]," that couldn't keep the singers apart for long. Less than two weeks after calling it quits, they step out in L.A. – a move reminiscent of Mayer's two-year off-and-on relationship with Jessica Simpson. Together again, the couple keeps it light and fun with a September getaway to Las Vegas, where they meet up with some pals at a strip club.
