Yes, it is true. Drugs are apparently being used during the video, with Gayheart at one point saying she needs to lay down because she's too high. The model called Peniche is also shown reading credit card numbers into a phone, leading some to speculate she's being paid for her time with the couple. An edited version of the tape is up over at Gawker's site.
The tape has apparently come to light as authorities investigate Peniche for allegedly working as a madam for high-priced escorts. According to Defamer, Peniche would redirect men who hit on her at clubs to call her escort service. Peniche was also recently seen on Dr. Drew's Celebrity Rehab, being treated for sex addiction. She was eventually kicked off the show for entertaining some seriously shady friends at the treatment center, and for stealing from her roommates, Mindy McCready.
