The footage is believed to be old since she and husband Ryan Edwards recently quit the show.
She told E! earlier this year, 'We're not returning to Teen Mom this season.
'The network told us they don’t want to show Ryan as a recovering addict. But they did want to enter a contract with our unborn baby and have the baby film with Ryan’s parents so it would look like someone else is raising it.'
Just days after Mackenzie's announcement that the couple would not be returning to the series, Edwards was arrested in Tennessee for 'simple possession of heroin.'
The 30-year-old was released a week later but is 'in complete denial' about his substance abuse issues, and 'refuses to go to rehab', sources told Us Weekly.
Mackenzie and husband Edwards are expecting a child later this year.
