You've probably stumbled upon a few gifs of a girl biting her lips, and wondered who it was. Well, I'll be the enlightener in this case; the girl you most likely saw was Gina Carano. Ms. Carano is a professional MMA fighter, which means basically, she can kick your ass, my ass, or both of our asses at the same time. She generally walks around at 140ish lbs at a height of 5'8". Make no mistake though, those pounds of weight contain nearly no fat. She started off her career in the sport of Muay Thai, but now has made numerous appearances on Showtime EliteXC cards as well as fights in Strikeforce.
Besides fighting, Gina has also appeared in the films Ring Girls as well as the kickass movie Blood and Bone by Michael Jai White. If you haven't seen Blood and Bone yet, go and see it right now, it is awesome.
Now for the good part..First, here are some of the most popular gifs of Gina floating around on the net. Gina seems to love biting her lips, and boy, I don't mind one bit.
