But the caption she wrote to go along with the photo has fans wondering if she was dissing her ex Justin Bieber, 19. "I thought he only liked the Latina category. Smh... #nomakeup#hatewhengirlssaythat," wrote Gomez, 21.

There's been online speculation that Gomez, who's Latina, was referring to new reports that Bieber spent a wild night at an Australian strip club near Brisbane on Nov. 26 -- just a few weeks after he got close to a slew of women during his tour stops in South America.
