After 8 years away from the WWE ring, Melina briefly returned to the federation on 22 July 2019 to celebrate the RAW Reunion. On that occasion, she took on the role of special referee in the backstage during Candice Michelle's match against Kelly Kelly for the WWE 24/7 Championship.
In March 2004, Perez signed a contract with WWE, and was assigned to OVW, WWE's developmental territory, where she began managing Johnny Nitro and Joey Mercury, dubbed MNM, to three reigns as WWE Tag Team Champions, as well as Nitro to two reigns as WWE Intercontinental Champion.
Perez is a three-time WWE Women's Champion, and a two-time WWE Divas Champion. Speaking with Fightful, she reflected on nearly getting on Tough Enough: “I totally remember just going from room to room and different things to do when it comes to filling out your application; and then another room, then you have to get interviewed; and then another room for your physical, and then another room to talk to everybody; and a waiting room.
There’s just so many places to go and there’s just so much to the process just to get that first initial shot to be seen. And that’s not even getting to the first episode”.
