Taylor Swift’s lawyers aggressively hit back at a former Last Vegas showgirl who’s suing the pop star for trademark infringement.

Maren Flagg sued Swift in March, claiming the singer’s latest album, “The Life of a Showgirl,” infringes upon her 2015 trademark of the phrase “Confessions of a Showgirl,” which Flagg has used to build up her own brand.

Flagg — who goes by Maren Wade when she performs — is asking for Swift to be immediately blocked from selling related merchandise as they battle in court.

Swift’s lawyers blasted Flagg and her lawsuit in a brief filed Wednesday.
