Apparently, Teen Mom 3 star Mackenzie McKee did make a sex tape and somehow porn giant Vivid Entertainment (the same company who released Farrah's video) got a hold of it, TMZ reports. They can't release it without Mackenzie's consent, though, and not only does she not consent, she had her lawyer write a letter acknowledging the tape and saying they'd better not release it. It was probably written in more sophisticated legal terms than that, but that's the gist of it.
Sex tape aside, Mackenzie has been busy doing other things - like being a mother to her two adorable children. And she DID recently release a video, but a very different kind. The reality star put out a music video called "The Sweetest Treat" help educate kids with Diabetes by giving them some healthy lifestyle tips. She's also donating a percentage of the profits to Diabetes research.
