Selena Gomez might have the case of the green-eyed monster. Rumour has it that the Latina isn't happy with Justin Bieber's current music partner, Miley Cyrus. Sources claim that Gomez has threatened Bieber to stay away from Miley Cyrus.

With Cyrus' engagement on the rocks with Liam Hemsworth, Cyrus is as single as ever. This of course has brought smiles to the fans of "Jiley." Since Cyrus was spotted at Bieber's Calabasas home, rumours have flown that a romance has been brewing. Of course, all of this was plain gossip given the only reason Cyrus was at Bieber's pad was for a music collaboration.

Of course, Selena Gomez didn't quite like the idea and has allegedly threatened Bieber to stay away from Cyrus. Gomez and Cyrus might have shared their past beau, Nick Jonas but Bieber is a different story. The 20-year old singer wants the Canadian crooner all to herself.

"Justin and Miley hooked up a few years ago," claims a source to Life & Style, adding, "Then he started dating Selena. It created this whole jealously thing between them. Now Selena doesn't want Justin anywhere near Miley - and they've been fighting about it!"

Miley Cyrus and Justin Bieber have been spending an awful amount of time with each other. This has led Selena Gomez to become paranoid over the thoughts of cheating especially with Miley involved.

"Selena is repulsed by Miley!" added the source. "Justin did the show anyways, which didn't sit very well with Selena. He's been continually choosing work over Selena and she's finally had enough."

Hopefully, all this talk is plain gossip. For one, Selena Gomez is the least bit "repulsed" with Miley given she expressed her adoration for the former Disney star during a radio interview. Gomez had called Cyrus "beautiful" after being named Maxim's Hot 100 number 1.

Still, "Jiley" fans hope Justin Bieber dumps Selena Gomez for Miley Cyrus.
