This past weekend at the Grammys, Taylor Swift launched into a performance of her hit "All Too Well," but was joined on stage by a surprise guest.

Right in the middle of the performance, Street Fighter's Ryu hopped on the piano and delivered a series of blows to the starlet's head. While it appears Swift may have been unfazed, her reaction later in the night during the album of the year announcement indicated otherwise to doctors on site. After administering a concussion test, it turns out the twenty-something songstress may indeed have been seeing red.

Still, she managed to take those kicks right on the chin and keep on rocking. Maybe the next challenger will have better luck in taking Taylor down.
