Machine Gun Kelly, the 34-year-old musician known for his wild antics and turbulent lifestyle, has recently opened up about a personal transformation that has had a profound impact on his life and relationship with actress Megan Fox. The couple, who have been under intense media scrutiny since they first got together, were reportedly on the brink of a split due to Kelly's self-destructive behavior. However, in a surprising turn of events, it was his secret decision to get sober that ultimately saved their relationship.

According to sources close to the couple, Megan Fox, 38, had reached her breaking point with Kelly, whose real name is Colson Baker. "She wasn't going to stay with him, not after the way he was acting, destroying guitars, smashing glasses on his head, and raging at anyone who got in his way," an insider revealed. "He was headed for disaster until he made up his mind to change."

The turning point for Kelly came when he quietly checked himself into rehab a year ago, a move he did not disclose to the public until a recent appearance on Bunnie Xo's "Dumb Blonde" podcast. "I didn't tell anybody outside of the [people] closest to me," Kelly admitted. "That was my first time I ever went to rehab. They just gave me so many ways to operate the body and show where this anger is coming from and methods to quell it."

Since completing his rehab program, Kelly has embraced sobriety fully. "I don't drink anymore. I'm completely sober from everything," he shared, reflecting on his journey to overcome his addictions to alcohol, marijuana, and prescription pills like hydrocodone and Percocet.

Megan Fox played a crucial role in supporting Kelly through this challenging period. "Megan has been extremely helpful in dealing with the kind of psychological withdrawals that come with getting off drugs," Kelly acknowledged. Her unwavering support, according to those close to the couple, was instrumental in his recovery and in keeping their relationship intact.

The pair, who have had their share of ups and downs, appear to be stronger than ever now, thanks to the significant lifestyle changes Kelly has made. "They've tried living apart and realized they missed each other too much to go their separate ways - so they worked things out," another source disclosed. A major factor in their reconciliation has been Kelly's commitment to not only his sobriety but also to treating Fox with the respect and care she deserves.

"He's cut way back on his partying and drinking. He's also stopped acting so jealous and controlling, which was his biggest issue," the insider explained. These changes have not gone unnoticed by Fox, who is reportedly doing her best to ensure that Kelly remains accountable. "Megan has promised she won't let that happen. She won't ignore red flags this time and will keep her boundaries strong. She insists she'll leave if things get toxic - but for now, she's happy and wants everyone else to be happy for her."

For Kelly, the journey to sobriety has been one of self-discovery and growth. "I continue to embrace that this journey is gonna be hard for me, but I accept it and forgive myself. I'm just happy that I'm able to start to be comfortable enough to show people who I am because I kind of depended on my art to do that," he reflected.
