Wiz Khalifa and Rita Ora -- Teen Choice Awards Not a One-Off (VIDEO)

Wiz Khalifa and Rita Ora are pretty clearly together ... not for certain, but pretty clearly.

In the wee hours of Tuesday morning, they showed up together at The Nice Guy in West Hollywood for dinner. They didn't mind the cameras and walked in together and out together.

The pair got all snuggly Sunday, backstage at the Teen Choice Awards.

Amber Rose and Rob anyone?
