Country star Billy Currington is sporting a gash above his lip after he was involved in an accident in the ocean. A "big wave" hit the "Good Directions" singer's paddle during a day out at the beach on Monday, and his teeth pierced his skin. Currington has shared a picture of his injury on his Twitter page, and asked fans for their medical advice. In a post, he writes, "Big wave just smashed paddle n (into) my face. Teeth went thru (sic) lip anybody know how to heal this hole without stitches?"
