Pop star Taylor Swift on Friday won an important ruling in the trial stemming from her allegation that she was groped by a Colorado disc jockey, with the judge dismissing the DJ's rival claim accusing the singer of wrongfully getting him fired.

The ruling by U.S. District Judge William Martinez left intact Swift's assault and battery countersuit against David Mueller, who asserts he was falsely accused by the recording star and ousted from his $150,000-a-year job at radio station KYGO-FM under pressure from her.

The Grammy-winning artist, known for such hits as "Fearless" and "I Knew You Were Trouble," reacted to the decision with tears of joy, embracing members of her legal team and family members with bear hugs in the courtroom.
