Mendez began her professional wrestling career in 2007 in New Jersey's independent circuit. She signed with WWE in 2009 and spent two years in its developmental branch, Florida Championship Wrestling, before her promotion to the main roster. In 2012, she rose to prominence through storylines with her "mentally unstable" character, such as high-profile relationships and a three-month stint as the General Manager of Raw. In subsequent years, she won the Divas Championship a record-tying three times[a] and held the title for an overall record of 406 days. She also won the Slammy Award for Diva of the Year in 2012 and 2014, and readers of Pro Wrestling Illustrated voted her Woman of the Year from 2012 to 2014. She initially retired from in-ring performing in April 2015, but returned to WWE over a decade later in September 2025. After six years away from the wrestling industry, Mendez joined the WOW – Women of Wrestling promotion as an executive producer in October 2021, serving alongside Jeanie Buss. This announcement coincided with WOW entering into a multi-year distribution agreement with ViacomCBS, the biggest distribution opportunity in the U.S. and abroad in the history of women's professional wrestling.[148] Beginning in September 2022, Mendez provided color commentary for WOW's syndicated weekly television program.[149] By August 2023, Mendez said she would be departing WOW at the end of her season-long contract
