Selena Gomez Sexily Straddles Justin Bieber On Holiday

There is something a little wrong about seeing Justin Bieber and Selena Gomez get their freak on whilst on a romantic holiday.

OK, call us old fashioned but at 17 and 18-years-old, the pair just seem like children and seeing such a public display of affection as this, makes us feel a little weird.

The pair are currently holidaying in Hawaii and have been spotted enjoying the good weather and crystal clear waters but these latest pictures show the pair getting hot and bothered!

Selena is seen straddling Justin as he holds her around his waist and kisses her passionately. We hope his mother doesn't see these!
