Ronda Rousey is arguably the biggest star in the UFC both inside and outside the Octagon, and her appeal is reaching a worldwide audience as evidenced by the latest commercial featuring the women's bantamweight champion in Brazil.

Rousey is set to fight in the South American country for the first time this weekend against Bethe Correia at UFC 190, and Budweiser has featured her in a new commercial ahead of the pay-per-view card from Rio de Janeiro.

"You have to have fear in order to have courage," Rousey says in the minute-long advertisement for one of the UFC's biggest sponsors. "You're not just training to be the best in the world -- you're training to be the best in the world on your worst day."

Rousey is currently plastered all over American television for her latest commercial working with Metro PCS, and that comes after she starred in two separate movies this year -- "Furious 7" and "Entourage."

Oh yeah, and she was named the most dominant athlete in all of sports.

The entire commercial showcases Rousey in a "Rocky IV"-like training montage, but chances are she's not incorporating a Budweiser into her preparation for the upcoming fight.

Then again, if Correia hopes to survive longer than Rousey's last three opponents -- a combined one minute and 36 seconds -- she might want to send the champion a few extra cases with hopes that she drinks a few before they fight at UFC 190.
