The Katy Perry love saga continues!
Katy and Diplo were spotted at two separate events together on Monday night.
The first was a sushi dinner with friends at Andrea's at Encore, followed by a birthday party at XS in Vegas.
According to reports, a well-disguised Katy twerked along to the music as Diplo DJ'd; he even played Dark Horse for her!
