'Teen Mom 2' Star Corey Simms' Mom Defends Son, Wife Miranda Against Leah's Claims

Following a year plagued with cheating and drug rumors, the Teen Mom 2 star is looking forward and staying positive about her future.

"Let's make it a great year!" read a re-tweet posted to Calvert's Twitter account on Thursday. Along with a message was a photo of "2015," with the "0" replaced with a heart.

Throughout 2014, Calvert has been dodging rumors. In October, her husband Jeremy took to Twitter, where he told his thousands of fans she cheated on him with her ex-boyfriend Robbie Kidd (the same man she slept with days before her wedding to Corey Simms). Next, the reality star was accused of being addicted to pills.

In an interview with In Touch Weekly, Calvert's alleged drug dealer claimed she was spending up to $1,000 on pills per week, and picking up 30 to 40 painkillers, including Vicodin, Lortab, Percocet and oxycodone, at a time.

“I’ve seen Leah pop a handful of pills, chew them like they were candy and swallow them," a source told the magazine. "She doesn’t even need anything to wash them down with."

Also on Thursday, Calvert re-tweeted Tyler Baliterra's announcement of his daughter's birth.
