Looks like the friendship between Selena Gomez and Kendall Jenner could be totally ruined over lothario Justin Bieber.

Last month, HollywoodLife.com reported that Jenner and Bieber, who have gotten much closer since their intimate photo shoot for Vogue's April 2015 issue, were enjoying their "friends with benefits" status.

"They love telling people they're just friends, but they're playing with everyone - there is more to it," a source revealed. "They've hooked up in the past, and there's still something there."

With that being said, Gomez reportedly "feels totally lied to, betrayed and stabbed in the back" after finding out about Jenner's secret affair with on-again, off-again boyfriend Bieber, according to another source.

The source alleged that the "Keeping Up with the Kardashians" star kept insisting she and the Canadian pop singer were "just friends," even when "The Heart Wants What It Wants" crooner texted and confronted her.

"[Gomez] doesn't even consider Kendall a friend anymore," the source added.

However, Gomez has nothing to worry about, as Bieber's hooking up relationship with Jenner is now rumored to be over.

The "Boyfriend" hitmaker was spotted "grinding" on model Josie Canseco at Nylon Midnight Garden Party on April 10, which the "KUWTK" reality star was upset about, according to In Touch.

A source claimed that Bieber treated Jenner "like a hanger-on" the following day.

"She left crying, saying, 'Justin's a d----- bag,'" the insider claimed, adding that the "Baby" singer even "brought girl after girl to his room" that night.

Moreover, Bieber reportedly contacted his Gomez following her recent split from Zedd.

"Justin reached out to Selena immediately after he heard about her ending things with Zedd," a source told HollywoodLife.com. "Not so much to try and hook up, but to check in with her."
