Carl's Jr. has signed MMA fighter Ronda Rousey as the brand's next model for a new marketing campaign.

In response to Rousey's maintaining her undefeated status in her latest victory against Bethe Correia Saturday, the burger brand tweeted a .gif with the message "Congrats on another big win, @RondaRousey. Can't wait to introduce people to your sweet side in 30 days."

In the past, Carl's Jr. has employed other celebrity spokeswomen, such as Paris Hilton, Kim Kardashian, Charlotte McKinney and Adrina Patridge.

"Aside from a variety of other factors, [Rousey] was chosen because she is loved and respected so much by both men and women," a Carl's Jr. representative told People.

This isn't Rousey's first time on screen outside the ring. The 28-year-old has also appeared in Furious 7, The Expendables 3 and Entourage.
