The Spring Breakers star traveled to Oslo, Norway to be with the pop star, who performed a concert there Thursday. And the two have left no doubt that their romantic flame has reignited.
“They were holding hands, hugging and they kissed on the lips,” a source tells PEOPLE. “They looked really in love, like no fights ever happened before. It definitely looked like they were back together.”
While Bieber, 19, and Gomez, 20, split back in November, they have kept in touch.
In late-March, the pop star was spotted visiting the actress’ Los Angeles home.
While a source told PEOPLE at the time that Gomez was “becoming more and more comfortable with her decision [to split],” it appears she kept some good will for him. “She wants the best for him,” said the source.
Bieber will remain in Europe for dates on his Believe tour. His next scheduled show is Saturday in Copenhagen.
