Former Olympian Ronda Rousey has made history as the first female MMA fighter to join the UFC!

The 25-year old Rousey has joined Dana White's MMA organization--and automatically becomes the women's 135-pound champion.

Rousey is apparently not going to be the last woman to join UFC, as there is already talk of her defending her title in 2013. Possible opponents include Sara McMann, Cris Cyborg and rival Miesha Tate.

Rousely has been fighting in Strikeforce since 2011 and has been kicking ass ever since. Check out her moves in the video below, but if you're a little squeamish, be forewarned that she breaks another girl's elbow in one of her fights!
