LOS ANGELES – UFC women’s bantamweight champion Ronda Rousey was all smiles as she spent time with the media at today’s UFC 184 Ultimate Media Day.

But Rousey’s (10-0 MMA, 4-0 UFC) expression took a quick turn when challenger Cat Zingano (9-0 MMA, 2-0 UFC) was brought on stage for a traditional pre-event staredown.

Rousey’s trademark scowl was on full display as fans and media saw the two undefeated women face-to-face. To her credit, Zingano appeared unfazed, and Rousey actually took the time to shake her opponent’s hand before she walked offstage.

Check out the video above to see the engagement.

Rousey and Zingano headline Saturday’s UFC 184 event, which takes place at Los Angeles’ Staples Center and airs on pay-per-view.
