Heidi Montag is no stranger to the cameras – or controversy – but she’s not checking into Dr. Drew Pinsky’s Celebrity Rehab for pill addiction.
“No, I’m not joining the cast, she tells PEOPLE exclusively, shooting down a report that claims the former Hills star was dropped off at treatment two days ago and is sharing a room with Real Housewives of D.C. star Michaele Salahi on Rehab.
“I’m actually on my way to see Just Go With It for the first time,” she says, finally getting to see her feature film debut. (Montag has a cameo in the Jennifer Aniston, Adam Sandler flick).
