On-again, off-again, on-again? Katy Perry and John Mayer's short relationship has been tumultuous to say the least, but it seems like the love birds are keeping things hot and heavy for the time being.

The couple spent a night out in Hollywood on Nov. 10 to celebrate the birthdays of HelloGiggles blogger Sophia Rossi and "New Girl" co-creator Liz Meriwether. According to an Us Weekly inside source, Perry and Mayer looked "so affectionate" together.

"John had his hand on Katy's back a lot, and they were kissing and holding hands," the source says. Apparently the couple looked like they were "full-on dating."

Also in attendance were Jon Hamm, Nicole Richie, Mindy Kaling and "New Girl" star/Hello Giggles co-founder Zooey Deschanel. And yes, before you ask, she and Perry were "joking about how they look alike."
