Justin Bieber‘s recent Instagram postings have fans wondering if he’s upset about the rumors regarding a new romance between his ex-girlfriend Selena Gomez and Charlie Puth.

Earlier this week, multiple reports alleged that Gomez, 23, and Puth, 24, were in the early stages of a new relationship. “It’s not serious, but she’s super into him,” a source told Us Weekly about the pair.

“They are both not out to hurt each other and really dig each others company, but they are not going overboard with things,” another purported insider told HollywoodLife.com. “Charlie is more into it than her, but she is willing to give things a chance. They are taking things day by day.”

As for Bieber, who posted a throwback kiss pic with Gomez on Instagram earlier this month, he apparently wants Gomez back in his life. “He’d love to be with her, but she won’t go for it,” a source told Us Weekly.

Bieber seemed to prove that he’s been pining for his ex when he took to Instagram to post a quote attributed to Buddha that reads, “In the end only three things matter: how much you loved, how gently you lived, and how gracefully you let go of things not meant for you.”

If Bieber was referring to Gomez and Puth, he may have jumped the gun. According to Puth, the two are just good friends. “We’re friends, and I’m very happy to have collaborated with her. She’s a really awesome singer,” said Puth, referring to his song with Gomez, “We Don’t Talk Anymore.” He added, “We did a song together and people think that there’s more, but we just musically collaborated.”

Even if Gomez isn’t with Puth, Bieber still might have another guy in his way – Samuel Krost. Gomez has been linked to Krost since last fall, when they were first pictured together. And the two were pictured again holding hands exiting a club Thursday night.
