"Reuniting again after a well-known break-up, Katy Perry and John Mayer have reportedly been spotted cozying up around Tinseltown.
On Saturday (November 10), the on-again couple attended a party at St. Felix in Hollywood to celebrate the birthdays of Hello Giggles blogger Sophia Rossi and "New Girl" co-creator Liz Meriwether. At the bash, the "Wide Awake" singer and her 35-year-old beau looked "so affectionate," according to an Us Weekly source."
