Nude Photos, Dark Secrets, & More! Inside Selena Gomez & Justin Bieber's EXPLOSIVE Feud

The feud between Justin Bieber and Selena Gomez may be far from over! After the two battled it out in a very public feud on the "Sorry" singer's Instagram account, both of them might be ready to take it a step further!

"They both always figured they had too much dirt on each other to ever go public," a source told Life & Style magazine. "But now Selena is ready to spill and so is Justin. They're both in big trouble."

And it looks like Selena is ready! "She's even talking about giving out pictures of Justin doing things he would never want the public to see," the insider added.

However, Justin can play that game too! "They have tons of nude shots of each other, and they've also videoed each other partying hard," the source dished.

But the nude photos aren't all! "Selena says she knows the truth about Justin's Calvin Klein ad," the insider revealed. "He stuffed his pants. Then he asked for it to be digitally enhanced!"

The "Hands To Myself" singer even might pull a Taylor Swift move and write a song about it all, too!

The insider explained that she is considering writing it about "all the awful things Justin did." Yikes!

"Justin and Selena know each other's darkest secrets," the source said. "This is the beginning of a huge fight, and there's going to be a lot of suffering."
