Katy Perry and Orlando Bloom had dinner with friends in Silver Lake Thursday night, but left alone in his car which means, if you couldn't tell by now  -- they're totally banging! Maybe. Probably. 

They've been inseparable since hitting it off at a Golden Globes party in January, even taking in last week's Adele concert together. 

Katy got to sit shotgun this time. He'll be opening her door in no time.
