Katy Perry is falling in love with John Mayer.
The Wide Awake singer - who divorced British comedian Russell Brand in December after 14 months of marriage - was spotted being very affectionate with the womanising musician at a joint birthday bash for Hello Giggles blogger Sophia Rossi and New Girl co-creator Liz Meriwether over the weekend.
Insiders say she is "obsessed" with him now.
A fellow party guest told US Magazine: "John had his hand on Katy's back a lot, and they were kissing and holding hands."
The couple's date at the party - which was also attended by A-listers Jon Hamm, Mindy Kaling, Nicole Richie, Shannon Woodward and Zooey Deschanel - is the latest in a string of romantic high profile outings for the duo since they rekindled their romance in September following a brief split in August.
