Good news: Olivia Newton-John is kicking cancer's butt.

"Olivia is finishing her treatments and is excited to see her fans when she begins performing again next week," a rep for the Australian music icon revealed to Entertainment Tonight this week.

The Grease star, who first battled breast cancer and underwent a partial mastectomy in 1992, announced a relapse back in May, canceling part of her tour to seek treatment.

in a video shared to promote the Olivia Newton-John Cancer Wellness and Research Centre's We Go Together campaign, Newton-John, who shared that she is "feeling better," thanked fans for their support.

"I’d like to express my gratitude to all of you who sent such kind and loving messages of support over the past few months," she said. "Your prayers and well wishes have truly helped me, and continued to lift my spirits."

Newton-John's tour resumes August 24 in Evansville, Indiana at the Victory Theatre.
