Justin Bieber and Selena Gomez

So it’s safe to say Justin Bieber and Selena Gomez aren’t hiding their relationship anyway. In fact, they’re all over each other in front of the paparazzi while vacationing in Hawaii. Girl gone wild!

Selena was photographed straddling Justin in the water in Maui on Thursday afternoon. They hugged, kissed and he even grabbed her ass a few times. Kids these days, they grow up so fast.

They went parasailing and jet skiing later in the afternoon, and that included a few more ass grabs on Justin’s part.

"1,200 feet in the air...not the best feeling," he tweeted. The best feeling? The way his girlfriend’s ass feels.

These photos are a little R-rated—especially for a Disney star. Maybe wrapping your legs around your under-aged boyfriend isn’t the greatest thing for your image, Selena.

Am I the only one that finds it strange that no one cares about the fact that Selena is 18 and is straddling her under-aged boyfriend? Justin’s only 17. I’m just pointing out the obvious.

And of course the photos are getting mixed reviews from Beliebers. Some fans think they look cute together and others are already busy writing Selena some death threats.

Do you think the photos are too much for young stars? They obviously knew the paparazzi was taking photos of them because they’re just a few feet away. Or are they free to do whatever they want because they’re on vacation? Share your thoughts below.
