Once again, Justin Bieber has gone shirtless for the summer on social media.

The "Heartbreaker" singer, 19, who just reunited with girlfriend, Selena Gomez again, has posted numerous steamy selfies over the last few months on Instragram. According to Hollywood Life, he "knows that his legions of fans can't enough of his fine physique, and he's been taking every opportunity to share that sweet skin with the masses." 

His 9,810,247 followers have had quite a treat with his "shirtless free-for-all," noted HL. "It's a magnificent use of multimedia, truly," they wrote.

But, Bieber has waned a bit on posting photos since reuniting with Gomez over the Fourth of July weekend. He has only posted one shirtless shot lately, and that's odd given his frequent need to seize opportunity and snap himself. HL wondered if Biebs was posting the photos in such a high capacity to get Gomez attention after their latest split, and has stopped now because they are back together.

His photos have showed off the talked-about "signature selfies pout," and his fans are getting closer to using the photos to chart Bieber's ever-changing moods, according to E! Online.

He also has some hot shots on Facebook and Tumblr.

The baby-faced crooner began his sexy selfies assault on June 20 when he posted an Instagram video, which is below. Check out the clip, click through the slideshow and drop a comment below!
