Selena Gomez and Justin Bieber have split up but rumors suggest the former couple might not even be talking to each other anymore.

The "Slow Down" singer hasn't spoken to Justin Bieber since mid-August since she's been travelling all over the world for her "Stars Dance" tour, a source revealed to HollywoodLife.com.

"Justin who?," the source jokes. "She doesn't talk to Justin at all ever anymore."

Selena Gomez and Justin Bieber have called it quits and have reportedly moved on from each other, but many fans are saying Miley Cyrus and the "Heartbreaker" singer would make a good couple following her split from Liam Hemsworth.

Miley Cyrus and Liam Hemsworth were engaged and dated for several years, but now they called off their wedding and are finding new romance. Many have pitted the "Wrecking Ball" star and the teen heartthrob as attention-seeking celebrities who both share many personality traits.

Rumors have been flying that Selena Gomez is dating George Shelley of Union J but those claims are not true - a major gossip site is claiming that Gomez does not have a boyfriend, following her high-profile break up with Justin Bieber, ClassicalLite.com writes.

Since these revelations, however, E! News has reported that Selena and George are not an item and claims that they were never together and the confusion stemmed from the video Selena recorded, ClassicalLite.com also writes.

According to the rumors, Selena, 21, and George, 20, reportedly took the next step in their relationship when she flew his whole band to Portugal to open for her concert in Lisbon on Sept. 11.
