Misdemeanor assault charges against R&B singer and former Dancing With the Stars contestant Mario have been dropped -- and he tells UsMagazine.com he couldn't be happier.

"I'm glad to be finally vindicated," he tells Us. "I want to thank everyone who believed in me. I will continue to love and support my mother."

His mother had told police that her son shoved her into a wall recently at their Baltimore home. She was reportedly under the influence of drugs and alcohol at the time.

"His mom lied so the charges were dropped," a source tells Us.

Next up for Mario? "He's dealt with this by staying in the studio, readying his album for release early next year," his rep tells Us.
