Reality star Michelle Duggar has kept some big secrets under wraps over the years. While Michelle waxes poetic on 19 Kids and Counting about the importance of living a squeaky clean and honest life, she's been hiding some alleged dirt of her own.

Fans of 19 Kids & Counting might have noticed the odd fact that Michelle rarely talks about her extended family on-camera. One might reason that her silence is due to privacy concerns, but that theory doesn't add up when you consider that Jim Bob's relatives have made numerous cameos on the series. So, what gives? One likely scenario is that Michelle may be ashamed of her lesbian sister, Evelyn.

Evelyn, who appeared once on the show in 2008, is rumored to be on the outs with her younger sibling — a revelation that might surprise her family-oriented fanbase. Evelyn and Michelle reportedly haven't been pictured together since 2014.

If you ask Evelyn's partner of three decades, Sharon Callahan, the awkward situation might be beyond repair, thanks to Michelle's involvement in the Quiverfull movement. The Quiverfull movement supposedly preaches anti-LGBTQ views — a suspicion that Callahan finds concerning. According to The Daily Mail, Callahan said in December 2014,

"We are worried about them. We have often thought that QuiverFull is a cult. It appears to be brainwashing to me." Keep watching to learn about more Dark Secrets Michelle Duggar Tried To Hide From Everyone!
