Two decades after they hit No. 1 on the Billboard chart for their hit song of the same name, Brandy and Monica added a blast of nostalgia with a brief cameo as news anchors in the Catwoman-themed "Mine" music video that debuted on June 14.

In the video, Grande stalks Penn Badgley, who plays a newly elected mayor who releases stray cats into the streets of a city resembling New York to cure a rat infestation. Brandy and Monica introduce music video viewers to the story.

The reunion for Brandy and Monica in the Grande video paid homage to the original "The Boy Is Mine," which was released after a rumored feud between the pair. The songstresses later won best R&B performance by a duo or group at the 1999 Grammys.

The song comes off her new album, "Eternal Sunshine," released in March. The album traces the public response to her divorce from ex-husband Dalton Gomez and the alleged scandal involving her "Wicked" co-star and now-boyfriend Ethan Slater. Reports surfaced last year that the pair began dating while splitting from their then-respective spouses, including Slater's marriage to Lilly Jay.
