Selena Gomez & Justin Bieber get close in Hawaii.
Justin Bieber is definitely bulking up! The “Baby” singer stepped out shirtless in Miami, FL over the weekend showing off his fit physique. 

It seems the Biebs, 17, is having a little trouble sleeping and we’re not just talking about him waking up to cameras. The teen heartthrob tweeted: 

“Fell asleep at 7pm and woke up at 12. clock all messed up now.”

While in Miami, Justin showed up in support of his girlfriend Selena Gomez, 19, who performed last week. He was such an adorning boyfriend that he wore one of her merch shirts backstage!

Bieber’s shirtless pics come just a few days after we saw SelGo showing off her bikini bod in Florida. Click the pics below and be sure to follow Celebuzz on TwitterFacebook and Tumblr for more summer celebrity sightings.
