Justin Bieber tattoo sunglasses no shirt beach venice beach

If Justin Bieber is on a mission to make Selena Gomez insane with jealousy, he's doing a pretty good job!

The 20-year-old pop star took off his shirt and hung out with model Yovanna Ventura in Venice on Monday afternoon, and yup, this is the same chick he partied with in Las Vegas over the weekend. Biebs and Ventura were joined by Kylie Jenner, and the trio posted several snapshots on Instagram. When we polled our readers earlier today, 52% of you thought Biebs and Kylie have already hooked up, 15% of you said no way and over 30% of you said not yet, so who knows who Bieber is getting down with at the moment! But seeing as Kylie is currently in NYC (and Selena too!), it's neither one of them ... but we still have a few days before the end of the week.

It's not just about the ladies though -- Bieber has had quite a few social engagements over the last few days with his bros! After watching boxer pal Floyd Mayweather win in Sin City on Saturday night, Bieber jetted to Washington to hang with Seattle Seahawks quarterback Russell Wilson. The duo went to church to hear Pastor Judah Smith speak, and they later went bowling at a local Lucky Strike.

Where's he gonna go next?!
