Everybody's favorite poster boy or whipping boy (take your pick) looks way serious with a fitness model he's been seen with over the past month.

Yovanna Ventura or Yo, as she likes to be called, is being hyped as Justin Bieber's post-Selena Gomez boo. Check it out everywhere online and what you'll see is The Bieb and Yo in various, uhm, romantic poses.

You'll also see Yo in, uhm, a lot of sexy selfies in bathrooms and elsewhere flaunting her hot and fit bikini bod. Mama mia!

And unless your elevator really doesn't go all the way to the top floor, the most obvious similarity between Yo and Selena is that these fantastic hotties are Latinas. Now we know what makes the Biebs' knees go weak.

The Bieb and Yo are flirting very publicly on Instagram. Some non-beliebers, however, say The Bieb is dissing Selena just to get her jealous. Really?

Just last week, Justin posted a pic of him and Yo, who was busting out in a sexy and cleavage-baring gown, and who had her arm on his shoulder The Bieb's caption read, "I see you In that Dolce Dress. Glad u had fun. :)"

Justin also Instagrammed a picture of the two of them on a hot beach date in Venice, California early this month.

But this Justin and Yovanna merry-go-round might be all smoke and mirrors. The Bieb might really have the hots for either Barbara Palvin or Adriana Lima, those Victoria's Secret models no red blooded male dare resist. At least, that's what the trending tells us.

Of course, Justin and Selena might not be officially over. Cooling off and all that or I deserve one more chance. Fat chance, Justin.

And there's the infamous Kylie Jenner that led to Selena calling it quits after she found out Justin and Kylie had their fling or two or three.

Which brings us back to the most vexing question of all: are Justin and Yo Official? The evidence, though circumstantial, seems pretty compelling. But what about all those other ladies swirling around The Bieb?

Here's what we know about this girl called Yo. She's all of 18. She speaks both English and Spanish. She's a fitness model and has signed up with Elite Model Management.

She's nuts about Instagram but doesn't tweet. She got 200,000 followers on Instagram. They say her fans keep tabs on Yo for her workout routine videos and dieting tips, but I guess their fan-aticism goes way beyond that.
