The event, which went down Dec. 28 at the MGM Grand in Las Vegas, Nev., featured a main event of Chris Weidman vs Anderson Silva, and a co-main that pitted UFC bantamweight champ Ronda Rousey against Miesha Tate.
"#UFC168 was literally the craziest thing I have ever seen. On so many levels. Holy sh*t," Marbles tweeted.
Marbles, 26, has a lot of Internet friends, 3.2 million to be exact.
She is a D.I.Y. digital entertainer who conceives of, stars in, shoots, edits and uploads her own videos — without the assistance of a major production company.
Teenage girls love her because she seems so genuine, and they tend to support whatever people and products she endorses.
Marbles' support for the sport can only help elevate the UFC's brand, along with women's MMA as a whole.
Her videos are catnip to young girls, the kind of thing they discover privately in their social media feeds, where her tell-it-like-it-is rants on sex, boys, sports bras and makeup speak directly to her core audience, 75 percent of whom are young women and girls, mostly from the ages of 13 to 17.
With Marbles' support for the UFC and Ronda Rousey, WMMA has an entirely new young crop of females that will potentially get hooked on the sport.
Props to Marbles for elevating one of the fastest-growing sports in the world by supporting the female fighters.
Plenty of other notable celebs showed support for Rousey following her UFC 168 victory, including critically-acclaimed actress Jada Pinkett Smith.
"My girl Ronda Rousey won tonight. Make them eat those boo's every time baby! We love you on this side," Pinkett Smith posted on her Facebook page following the win.
At present time, it's unclear how Rousey and Smith know each other.
