Mackenzie Douthit McKee no longer stars on MTV’s “Teen Mom 3" – the network canceled the series after one season in 2013 -- but that didn’t stop the former reality star was asking for her fans to fund a rumored upcoming breast augmentation, according to reports.

On Tuesday, TMZ reported that Mackenzie, 20, had created a profile on MyFreeImplants.com, a crowdfunding site in which users donate money to individuals for breast augmentations. On her profile, Mackenzie is said to have labeled herself as a “fitness nut” and shared that she wants to upgrade to a “full C cup” in order to make her body “more proportionate.” She reportedly wanted the plastic surgery in order to boost her chances of winning at fitness and bikini competitions. TMZ also claimed that while Mackenzie had only secured $20 of her $5k goal, but had procured Beverly Hills plastic surgeon Dr. Neal Handel to perform the procedure.

As other outlets have noted, the “Teen Mom 3” star did not request for her fans on social media to donate to the cause. On Wednesday, Mackenzie shot down the plastic surgery rumors on Twitter. “Not everything you read is true,” Mackenzie wrote after a fan tweeted her, asking about the allegations.

While Mackenzie has denied she plans to alter her breasts, the Ashely’s Reality Roundup is reporting that the MTV star previously shared her desired to receive a breast augmentation. But according to the site, her husband, Josh McKee, was not interested in the procedure. “Josh says he likes them the way they are and NO WAY can I get a boob job,” Mackenzie reportedly wrote on Twitter in August 2014.

Mackenzie wouldn’t be the first “Teen Mom” star to go under the knife. “Teen Mom OG” star Farrah Abraham has been vocal about receiving not one, but two, breast augmentations in recent years. “Teen Mom 2” lead Jenelle Evans’s breast augmentation was even a part of her Season 4 storyline.

Mackenzie, who has two kids with Josh, Gannon, 3, and Jaxie Taylor, 1, starred on the fourth season of MTV’s “16 and Pregnant” docuseries in 2012. In August 2013, she landed a starring role on the third edition of the network’s spinoff series “Teen Mom.” Three months later, after starring on 13 episodes with her co-stars Alex Sekella, Katie Yeager and Brianna DeJesus, the network announced that the show would not be renewed for another season.

"We’re thankful to Briana, Katie, Mackenzie, Alex and their families for sharing their stories as they navigate young parenthood and for helping to have a positive impact on the importance of teen pregnancy prevention," an MTV spokesperson told Us Weekly.
