Wow, these two sure grew up fast. As you can see in the pictures above, Selena Gomez and Justin Bieber just can’t keep their hands off of each other. The sexy Selena and the disgustingly scrawny Justin weren’t shy about showing off their affection while vacationing in Maui, Hawaii this past week. The photos reveal Selena straddling Justin, Justin grabbing Selena’s ass, Justin and Selena making out… ugh, I gagged a little. I love me some Selena, she’s got to be the hottest 18-year-old ever, but Justin, he’s an irritating 17-year-old brat – I don’t want to see him getting hot and heavy with the sextastic Selena!
