Justin Bieber has hinted he and Selena Gomez are officially back together.

The 19-year-old "Beauty and a Beat" singer - who was dumped by the brunette beauty in December after a tumultuous two year relationship - briefly posted an uncaptioned new photo of them cuddling up together on Saturday (right), but he quickly deleted it.

The Spring Breakers actress flew to Norway earlier this week to see the "Baby" hitmaker, who is currently on tour, and they were soon spotted kissing. "They were holding hands, hugging and they kissed on the lips. They looked really in love, like no fights ever happened before. It definitely looked like they were back together," a source previously said.

Pals recently insisted that despite their on/off relationship, the pair - who split late last year - can't stay away from each other and have an intense connection. "They are totally hooking up again. There is definitely some unfinished business there and they need to work things out," one friend said.

But friends close to Selena are not impressed that she is spending time with her ex-boyfriend again, despite the fact she wants to keep their relationship casual for the moment: "None of her girlfriends think it is a good idea. She's definitely not looking to get back with him for the long haul."

The duo broke up shortly after holidaying in Mexico where they had planned to ring in the New Year together but got into a huge argument on December 30 after she allegedly found text messages from other girls on his phone.
