Katy Perry Says Chill Out ... Orlando's Awesome

Katy Perry apparently has no issues with whatever happened in Vegas between Orlando Bloom and Selena Gomez, because she just pooh-pooed everyone who thought she was done or upset with her BF.

Katy posted on Thursday night, "Instead of giving energy & eyeballs to dumb conspiracy check out how COOL this is" ... linking to a Time article about Orlando Bloom helping Ukranian kids with their education.

It's so weird ... the day before she posted lyrics from Peggy Lee's song, "Is That All There Is" ... which is all about breaking up.

Love ... it's a confusing thing.
