"Teen Mom 2" star Leah Messer-Calvert is said to be renewing her faith amid reports of ongoing personal struggles.

The reality TV star was reportedly spotted attending a service at the Sissonville Community Church in Charleston, West Virginia on Nov. 22 where a source claims she appeared to be engaged during a sermon.

In recent months, the 22-year-old mother of three has alluded to marriage struggles in a series of cryptic tweets as divorce rumors continues to swirl. She is also believed to have abruptly quit the hit MTV reality show last week amid infidelity reports.

"She's started going to a church that embraces forgiveness and recovery. She's determined to make a complete turnaround," a source told InTouch magazine.

During the Nov. 22 sermon, Messer-Calvert's pastor was preaching about finding strength in Jesus to overcome addiction and substance abuse.

"He said that bad habits like drugs, sex and alcoholism can be broken when one finds Jesus. Leah was nodding her head in agreement the entire time," the source continued. "It seemed to really hit home for her."

The MTV star has been a cast member on "Teen Mom 2" for 5 seasons, however; she reportedly now wants privacy after having her entire life played out on television for so long.

"[She] doesn't want her drama on TV anymore," a source told Us magazine. "She's scarred by how her split with [ex-husband] Corey played out on TV."

On Sunday she responded to rumors that she cheated on her husband Jeremy with her ex-boyfriend Robbie.

"I am not with Robbie and I'm not pregnant. Jeremy and I are still married! … um... I'm def NOT pregnant lol," she wrote in a series of tweets.

Messer-Calvert, who became a first time Mom of twin girls at age 16, has had a difficult year. She continues to face a number of challenges including that of one of her twin daughters Aliannah, who was diagnosed with a very rare, incurable form of muscular dystrophy.

She is also currently in the midst of an ongoing custody dispute with her ex-husband and the father of her twin girls, Corey Simms.

Her faith has played a key role in helping her overcome the obstacles in her life as she continues to push forward.

"From now on I will give no reaction. I will let go, and let GOD. Everything happens for a reason!" she tweeted in Sept.
