Selena Gomez's former boyfriend was on a boat when this controversial pose happened, New York Daily News has learned. He was looking over the horizon, pointing a finger towards the green mountains.

He captioned the photo, "Look."

Bieber's snap got a lot of reactions from his Instagram followers — some liking it, while others not. However, the most controversial reaction to this outburst was Miley Cyrus', according to People.

The "Wrecking Ball" singer posted a close up picture of Bieber's butt on her Instagram account, captioning it, "Bieber VS Rihanna."

Bieber went to a tropical island with some friends following a religious conference trip to Australia.

The 21-year-old singer and his pals may seem to have a chill time, but on Monday, he shared a snap of Joe Termini lying down on a deck near the water, with a nasty wound from a shark attack, Seattle Pi reported.

The photo was captioned. "Exactly why I hate sharks they told us reef sharks don't bite."

Some of his followers wished his photographer to get well soon, while others placed comments that it happened because he [Termini] might have provoked them [sharks].

Later that day, he shed light on the incident and reminded his friend that it was 'Discovery Shark Week.' It wasn't confirmed though if Termini was bitten or just scratched.

Meanwhile, the Canadian singer will be having his European tour on Aug. 28–30 at Cofton Park in Birmingham, United Kingdom.

This event follows his controversial appearance on Ariana Grande's concert, which was rumored to be the reason why the Nickelodeon star and her then boyfriend Big Sean broke up.
