That there is Riley Cote, his girlfriend (seen hither), Kevin Harvick, and presumably some chick Carts wanted no parts of.
The picture is Cote's Facebook profile pic, taken at Dover on Sunday. Carts, of course, is chummy with Harvick. Surely you remember the pink racing helmet One Seven included in his favorite things basket, ostensibly making Harvick one of his, um, favorite things. Fun.
