"Justin wants Selena to be with him 24/7 right now but she's playing hard to get and it's really driving him wild," a source revealed to HollywoodLife.com. "The power has shifted in their relationship - he's the one doing the chasing right now."

The gossip website's insider also said that "they're always going back and forth, and up and down," explaining the pop stars' relationship is more like a "roller coaster" than anything else.

Um duh, HollywoodLife.com source.

"That lack of stability is a part of the excitement for Justin - it keeps him interested," the source continued to speculate. "Selena is the only girl in Justin's life that will stand up to him - she's the only girl who won't pick up the phone when he calls, and that's exciting for him."

So another day, another Justin Bieber and Selena Gomez rumor emerges. Though the "playing hard to get" story seems to be fathomable, these two are still not officially back together so let's take this rumor with a grain of salt, shall we?
