Ronda Rousey is already one of the most popular figures in mixed martial arts, but she just landed her most high-profile supporter yet.

UFC CEO Calls Ronda Rousey A 'Seminal Moment' in Culture

The UFC's undefeated bantamweight champion is scheduled to re-enter the Octagon against Cat Zingano on February 28th, as a co-headliner of UFC 184 at the Staples Center. And when that fight goes down, 'Rowdy' Ronda will know she has men's boxing superstar Manny Pacquiao cheering her on.

Rousey posted a video of Pacquiao to her Instagram feed on Monday afternoon, in which the eight-division world champ tells her "Good luck and may God bless you."

“So humbling to hear such kind words from a legend like @emmanuelpacquiao,” Rousey wrote in the accompanying caption to the video.
