Leah Calvert isn’t having the best week. Just five days after she unleashed a Facebook rant against her ex-husband, Corey Simms, and addressed rumors of her impending divorce from husband Jeremy Calvert, the “Teen Mom 2” star is now being accused of emptying her daughter Ali’s trust fund. InTouch Weekly is reporting that Leah, 22, stole thousands of dollars from her special-needs child.

In the Jan. 5, 2015, issue of InTouch Weekly, "multiple sources" allege that Leah took nearly $50,000 from Ali Simms, 5. The cash in the account, set up with money from MTV, was reportedly meant to be used toward the child's costly medical expenses and college education.

“The money in Ali’s trust fund was not supposed to be touched by anyone,” said an source. “It’s absolutely disgusting.”

Trust funds set up for Leah’s other two daughters, Ali's twin, Aleeah, 5, and Adalynn, 1, were reportedly not touched. Insiders told the tabloid they believe that Leah "totally drained" Ali’s account because it would be easier to cover up the loss. As most “Teen Mom 2” viewers know, Ali suffers from an incurable form of muscular dystrophy.

“It seems she thought Ali would be the easiest to take from because she could blame the missing funds on medical needs, like a new wheelchair,” said a source.

So why did Leah take the money? Some insiders told the magazine they believe the reality star withdrew from the account because she is “selfish” and enjoys buying pricey items like iPads and iPhones. Others said the MTV star, who recently signed on for Season 6 of “Teen Mom 2,” is strapped for cash following her rumored split from husband Jeremy, 25. While Leah claims her marriage to the pipeline engineer is still intact, Jeremy hasn’t been shy about hinting at their relationship troubles on social media in recent weeks.

Unfortunately for Leah, who only just settled a drawn-out custody battle with her ex-husband, Ali and Aleeah’s father, Corey, is reportedly upset about his ex-wife’s rumored actions. “He’s furious,” said a source. “Ali’s future has been wiped away and he’s seeing what he can do to get the money back.”

The allegations against Leah comes two months after the magazine published claims that the MTV star has been spending thousands of dollars on prescription drugs — such as Vicodin, Lortab, Percocet and Oxycodone — weekly, for years. “I used to give Leah the pills myself; she’s picked up 30 to 40 pills at a time,” a “drug dealer” told the magazine. “She was withdrawing $1,000 a week to buy pills.”
