They're still going strong!
So strong that they just can't keep their hands off of each other!
At least that's what we hear! Katy Perry and John Mayer were apparently SO into each other at their friend, Sophia Rossi's party at the Saint Felix in Hollywood on Friday night, they apparently were packing on the PDA like nobody's business!
Partygoers said they were being "so affectionate" with each other and we hear that:
"John had his hand on Katy's back a lot, and they were kissing and holding hands. [They looked like they were] full-on dating."
Just don't you dare hurt a hair on her pretty little head, John!
