As we all probably know, Miley Cyrus has dumped her previous wild image for the cleaner one. Thanks to her transformation and her happy relationship with Liam Hemsworth, the former Disney star is reportedly tackling all tapings of "The Voice" this season with a whole new healthy attitude.

"Miley is killing it on set at 'The Voice' this season," a source tells HollywoodLife.com. "It's mostly because she feels like an entirely different person. She has a new focus, clarity, and energy that has everything to do with her love for Liam."

In the past few months, Miley has been sobering up with more down-to-earth vibe. "Thanks to Liam's love, support and encouragement, Miley has gone super healthy, fully vegan, organic, and has cut off all intoxicants," shares the source. "Gone is the artist who sang about doing lines in the bathroom, now Miley has gone completely sober and her work on 'The Voice' has changed for the better."

"She has more energy, more enthusiasm, and her creativity is soaring. Last season producers had given her an extra trailer for her to imbibe in and this season that same extra trailer is used for her to practice yoga," the source adds.

However, despite her new healthy attitude at workplace, Miley was recently rumored to be feuding with fellow coach on "The Voice", Jennifer Hudson. The two reportedly couldn't "seem to get along" on the set. Miley and Jennifer will join Adam Levine and Blake Shelton as the coaches on the upcoming season of the show, replacing Gwen Stefani and Alicia Keys.

"The Voice" returns for season 13 on Monday, September 25 at 8 P.M. on NBC.
