Is Selena Gomez tired of 'clingy, delusional' Justin Bieber?!

Ever since TMZ reported that Justin Bieber and Selena Gomez are on the rocks, the tabloids have been having a field day speculating about their relationship. A couple of magazines have reported that Justin is the one who wants to end things because he wants to date other girls. But Star (via Celebitchy.com) claims that Selena is the one who wants to pull the plug because she's "tired of immature Justin and his attention-seeking antics."

"Justin's too clingy and delusional and she wants to date someone a bit more mature [editor's note: someone with bejeweled Family Guy bling and his own Batmobile isn't mature enough for her?]," a "source" tells the mag, adding that the two will probably be dunzo by the end of July.

According to Star's source, Selena and Justin have been "fighting frequently" and she "just doesn't want to deal with the drama anymore."

"She's worried that he's so unpredictable he could do something weird like a dramatic proposal to avoid being dumped. She just wants something more normal and chill," Star's snitch says.

Apparently Selena, 20, realized Justin, 18, was too immature for her after she worked on Spring Breakers with James Franco and Harmony Korine.

"Working on Spring Breakers was a major eye opener for her," the source tells Star. "She was spending a lot of time with older guys, and it made her want to start exploring her options. ... She and Justin have actually broken up a few times already. They always get back together because Selena ends up changing her mind."

So a few reports claim that Justin is planning to break up with Selena so he can be free to date other people, while others claim Selena is tired of Justin being so immature. Is this a case of both their camps leaking info to the media in a sort of "I dumped you"/"No, I dumped you!" pissing contest? Or is there truth to both sets of reports? Justin's 18 and probably doesn't want to be tied to one girl, and Selena's at an age where she's probably interested in older men. Who knows when it will actually happen, but it looks like the end is near for these two.
