In May 2013, JoJo joined WWE and E! Network's reality show Total Divas, which shows behind the scenes footage of select WWE Divas and a look into their personal lives.
At just 19 years old, JoJo made her main roster debut on the June 26, 2013, episode of WWE Main Event, singing the entrance theme for Tons of Funk alongside The Funkadactyls (Cameron and Naomi). The following week on Raw, JoJo appeared in a backstage segment also involving The Bella Twins, Natalya, The Funkadactyls, and Eva Marie. On the July 22 episode of Raw, JoJo along with the cast of Total Divas appeared on Miz TV, where she introduced herself to the crowd. JoJo sang the United States national anthem at SummerSlam on August 18.
On the August 26 episode of Raw, JoJo served as the special guest ring announcer during a singles match between Natalya and Brie Bella. After the match, WWE Divas Champion, AJ Lee interrupted Brie Bella's victory celebration by cutting a worked shoot promo on the cast of Total Divas. Following this, JoJo appeared at ringside to show support for her Total Divas co-stars during their matches. JoJo was booked in her first match on Raw on October 7, teaming with Natalya and Eva Mariein a winning effort against Alicia Fox, Rosa Mendes, and Aksana in a six diva tag-team match, however she was never tagged into the match. The Total Divas defeated The True Divas (Fox, Aksana, Divas Champion AJ, Kaitlyn, Mendes, Tamina Snuka and Summer Rae) in a elimination tag-team match at the Survivor Series pay-per-view, and the following night on Raw in a rematch, where she achieved her first in-ring victory after pinning and eliminating Tamina Snuka.
JoJo later moved to WWE's developmental territory NXT in late 2013, after it was confirmed she would not be returning to Total Divas for its second season. She subsequently became the ring announcer for NXT. In April 2015, JoJo was promoted to the main roster and began serving as the regular ring announcer on Main Event, SmackDown, Raw and pay-per-views as well as a backstage interviewer. She served as the Raw ring announcer from 2016-2018 and remained under contract until she quietly departed from the company in early 2021.
