While Jenelle Evans' abortion made the majority of the headlines Monday night, her MTV co-star dropped an equally shocking (albeit very different) bombshell.
Teen Mom 2's Leah Messer Calvert ended the Season 5 premiere with the news that her 4-year-old girl Aliannah has a rare form of muscular dystrophy.
Fans know that Leah and her former husband Corey Simms have spent years seeking answers as to why Aliannah was so developmentally delayed.
Now she finally has them, but that doesn't make it any easier to take.
Ali's condition is degenerative, according to experts, and will likely worsen as the preschooler gets older, eventually confining the poor thing to a wheelchair.
Fortunately, Ali is happy and content at present, but still. Life has dealt Leah A LOT in recent years, and it's hard not to feel for her deeply after this.
Aliannah and Aleeah are Leah's twins with Corey Simms, whom she married and divorced months later in a saga that played out at length on Teen Mom 2.
The two had their problems as a married couple, and were never the best communicators. Yet they remain a strong, united front when it comes to their daughters.
Leah has since remarried and has a daughter, Adalynn, with Jeremy Calvert. She miscarried the couple's first child prior to Adalynn, who she carried to term.
How do you think Leah Messer Calvert will handle the medical revelation regarding Ali? Only time will tell, but it won't be easy, and we wish her only the best.
