The crazy incident happened after the woman crossed his path on the paddock when she tried to snap a selfie with him at the Valencia MotoGP on Sunday.
Valentino Rossi appears to kick the woman with his left foot
The 37-year-old, who was on his bike at the time, appeared to stick out a foot and kick her on the back of the leg – leaving her with a "small bruise."
And according to a local radio station, the woman named as Ana Cabanillas Vazquez, is considering taking legal action against the hot-headed racer.
She said: "I was taking some pics with some friends in the paddock and I knew he was there but wasn't sure where he was, but then suddenly I felt a blow and a shove and when I turned around, I saw it was Valentino Rossi that had pushed me.
Rossi later joked that they may arrest him back in Italy
"I have a small bruise on my leg, and although it is not a lot, I still feel it necessary to report it. If he wasn't such a role model for people, I wouldn't bother, but why should he be allowed to behave like this just because he's in a bad mood.
"Although he has apologized, I have not accepted his apology, and I am thinking of filing a complaint." (Spoken like a true liberal)
