Kathleen Mary Leroux was an American Professional wrestler billed from New Orleans, Louisiana and was one half of the Nasty Girls tag team with Linda Dallas.

Kat LeRoux made her debut in 1985 as a 20 year old, after training with Killer Kowalski at his school in Malden MA.

Kat began her career as Misty Blue's tag team partner before turning against her joining former enemy Linda Dallas in Mad Dog Debbie's stable. The trio wrestled for many north eastern independents including IWF, ICW, USWF, NCW and others. They got their big break when (along with Misty Blue, Heidi Lee Morgan and Cookie Zula), the trio joined Crockett Promotions and stayed there from early 1987 to mid 1988.

Upon leaving Crockett they returned to the north east indie scene. In 1989 Kat wrestled for Delta Tiger Lillies, Florida Championship Wrestling and Joel Goodhart's TWA before joining Tor Berg's LPWA teaming with Linda Dallas as "The Nasty Girls". The company went into hiatus in 1991 and the Nasty Girls returned to the north east indie scene and toured Europe. Kat retired at the end of 1995.
