She later started competing on the independent circuit for multiple promotions in the United States for several years, most notably and commonly for Shimmer Women Athletes.

[2] She debuted on 23 June 2007, on her eighteenth birthday, at PWA Australia with a win over Eagles and Aurora, wrestling under her birth name as Jessie McKay.

[13] After Lane vacated her title due to injury, McKay won the PWWA Championship for the second time in a four-way match against Kellie Skater, Sway, and Shazza McKenzie on 14 September 2009.

[13] In September 2011, McKay failed to win a three-way match for the Shimmer Championship also featuring champion Madison Eagles and Nicole Matthews.

[15][21][25] As a result, later in September 2010, McKay was granted a title match against her trainer and former tag partner, Shimmer Champion Madison Eagles at Volume 35, but failed to win.

[1] McKay made her televised in-ring debut on the 10 June episode of NXT, where she competed in a losing effort against Becky Lynch under the ring name Jessie.

[48] Kay made her first appearance on the main roster on the 30 June episode of SmackDown, where she worked as a jobber losing to Dana Brooke.

[49] Kay finally made her return to NXT television on 27 July, where she achieved her first live victory in the company by defeating Santana Garrett.

[55][56][57] This ultimately led to a six-women tag team match at TakeOver: Toronto, which was taped and aired for the 23 November episode of NXT, in which Aliyah, Ember Moon, and Morgan defeated Kay, Royce, and their partner Daria Berenato.

[60][61][62][63] This resulted in a fatal four-way match, which also involved Nikki Cross, at the TakeOver: San Antonio event on 28 January 2017, in which both Kay and Royce failed to capture the NXT Women's Championship.

[73][74] Eventually, Naomi teamed up with Asuka but lost to the IIconics at the Super Show-Down on 6 October, held in the latter's homeland of Australia.

[75][76][77][78] Three weeks later, both Kay and Royce took part in WWE's first all-women's pay-per-view, Evolution; they were the first two eliminated from a battle royal for a future women's championship match.

[83][84][85] At the event, which took place on 7 April, The IIconics won the match after Kay pinned Bayley to win the Women's Tag Team Championship for the first time.

[86] On the 5 August episode of Raw, The IIconics lost the titles to Alexa Bliss and Nikki Cross in a fatal four-way match also involving the teams of The Kabuki Warriors (Asuka and Kairi Sane) and Fire and Desire (Mandy Rose and Sonya Deville).

[87] After a brief hiatus, Kay and Royce made their return on the 11 May 2020 episode of Raw, interrupting WWE Women's Tag Team Champions Alexa Bliss and Nikki Cross.

[97][98][99][100] At Bound for Glory, they defeated Decay (Havok and Rosemary) to win the Impact Knockouts World Tag Team Championship.

[108] On 16 May 2021, McKay, along with long time tag team partner and best friend Cassandra McIntosh, launched a comedy and variety podcast titled Off Her Chops.
