It seems Mackenzie Standifer will do anything to protect her man! In a sneak peek for the upcoming Teen Mom OG Season 7 reunion special, the reality star defends husband Ryan Edwards by getting in an intense argument with Dr. Drew Pinksy over Ryan's aftercare following his drug rehab last year.

Dr. Drew brought up how Ryan seemingly cannot follow doctor's orders when it comes to taking medicine to suppress his heroin addiction, and after a lot of talking over each other, Dr. Drew finally catches Mackenzie's attention. "Are you ready to listen to me?" he politely asks. Apparently, she wasn't. "EXCUSE ME? No, I’m not," she says back, looking for some support from Ryan, who would clearly rather be anywhere but there.

Dr. Drew proceeds to try to tell the couple that Ryan needs to take his medicine per doctor's orders "to the letter." He adds, "Then, I could argue to [Maci Bookout] that he’s under doctor’s prescription, he’s following it to the letter and you can check with that doctor and that doctor will take responsibility for any problems. But if [Ryan’s] taking [the medication] ad-lib, I can’t vouch for that."

Still clearly not getting through to Mackenzie, she replies, "I don’t think you can vouch for anything Ryan does, honestly. But that’s just my opinion." Sigh…

Earlier on in the reunion, Ryan claimed he skipped out on drug treatment before his March 28 arrest due to his reality TV fame. "It’s honestly hard to find a counselor because of this TV show. [A counselor] was like, ‘I’m not gonna see you because I don’t think the TV show and you are a good idea,'" he told Dr. Drew, who wasn't amused by the ridiculous claim.

It's no surprise the couple is reportedly in some serious denial about Ryan's addiction. "Mackenzie is in complete abject denial about Ryan’s drug addiction and issues surrounding how very, very serious it truly is," a source recently told Us Weekly. "Mackenzie only wants to focus on having his baby and seems to be hoping that this will help him to be inspired to live a clean and sober life." The source added, "Ryan denies the seriousness of the drug addiction, like any addict will do, and Mackenzie chooses to believe him." Hopefully they get their sh-t together before their baby arrives.
