Yet another reason to celebrate today, Ashley Harkelroad turns 26. This smoking tennis player was the cover model for a Playboy shoot in April of ’08. Apparently, this makes her the first tennis player to ever pose in her birthday outfit for the magazine in the history of the world. At one point in time, Ashley was ranked 61 in the world. While we are certainly not tennis fanatics, we’re pretty sure that for one brief, shining moment she was ranked 69th. Nice. Check out more of her pictures from that Playboy shoot and others after the jump!
