Justin Bieber & Miley Cyrus 'hook-up' rumors FALSE! 'Believe' crooner did NOT cheat on Selena Gomez with 'Bangerz' songstress, Twerker tweets 'I never read this sh*t!'

Miley Cyrus did NOT "hook-up" with Justin Bieber while he was dating with Selena Gomez... and the Bangerz songstress is sick of all the rumors.

Recently, the infamous gossip tabloid Life & Style reported that the "Come & Get It" beauty recruited BFFs Taylor Swift and Demi Lovato to seek "revenge" on 21-year-old Cyrus for her sneaky cheating ways. An alleged source close to Gomez reveals, "Both Taylor and Demi know how heartbroken Selena's been, and they hate what Miley did to her... All four girls used to be friendly, but when Selena heard Miley started making moves on Justin, it went downhill."

The magazine then claims, "by refusing to attend the same parties and club events as Miley - and trash talking her to anyone who'll listen - the trio are freezing Miley out of lucrative appearances that used to net her a jaw-dropping $300,000 a night." 

Yeah, okay.

Gossip Cop checked with another Gomez insider, who insists, "There is no conspiracy against Miley. These girls are way too busy in their lives to be participating in the nonsense described in this ridiculous story." 

And Cyrus agrees.

On Monday (Feb. 24), the controversial Twerker tweeted:

@MileyCyrus: "Btw this is photoshopped. Biebs wasn't at Pharrels bday party. I never read this sh*t & that's why."

Oh, and she's NOT set to play Tinker Bell in a live broadcast of Peter Pan:

@MileyCyrus: "I would rather choke on my own tongue."

Harsh... she would make a cute Tinker Bell (although a not-so-innocent one)!

Cyrus may not always read the over-sensationalized tabloids, but when she does, she's ready to fight1
