Cyrus and Schwarzenegger were spotted at On The Rox nightclub in West Hollywood on January 24, around 11:30 pm.
According to an eyewitness, they were there for a private party, and quickly moved to a more secluded back room.
Once inside, the eyewitness told Radar, Cyrus “lit up right away.”
"“It smelled like a joint,” the source told Radar. “And if you look at how thick the smoke is, it is clearly not a cigarette."
What would Schwarzenegger’s mom, Maria Shriver think? The source insisted that despite Cyrus’ public display, “Patrick did not smoke.
But the source said, “He didn’t care at all that Miley was smoking. She had more than one, many more, and they were both drinking.”
Fueled by alcohol, “They were so touchy and making out a lot,” the source claimed. “She sat on his lap the entire time.”
Cyrus, 22, has made no secret of her drug use in the past, insisting “weed is the best drug on earth!” Meanwhile, 21-year-old Schwarzenegger’s mom, Maria Shriver, is an anti-drug activist.
The next day, Cyrus posted a photo of herself from her night out, wearing Moschino.
She claimed she had been on her “best behavior.”
According to the source, Cyrus was “actually quite nice and chill.”
But the source said, "She has an ‘I don’t give a f**k’ attitude.
