Thanks to the anonymous fan that emailed The Hollywood Gossip these photos of Joslyn Noel Morse nude. The exotic dancer, known now as the mistress of married Yankees slugger Alex Rodriguez, appeared topless in a 2001 edition of Playboy's "Casting Calls."

Here's Joslyn Noel Morse nude, along with the New York Post cover on which her identity was first revealed. The photo of Joslyn cropped by the Post is the pic to its right ...

Alex Rodriguez, a.k.a. "Stray-Rod," was outed while dining at a steak house and visiting a high-end strip club, The Brass Rail, with the blonde dancer in Toronto this week.

TMZ reports that the pair were seen in Las Vegas together months before that, leading to speculation that A-Rod's liaison with Morse is an ongoing affair.

An Iowa native and veteran of several high-end Sin City strip joints, Joslyn Noel Morse was nowhere to be seen yesterday in Boston, where Rodriguez is in town to play the Red Sox.

Alex was accompanied by his wife, Cynthia Rodriguez, who was surprisingly all smiles. Maybe she's cool with the fact that her husband meets random strippers and flies them out for "companionship" on road trips. This is a man who yells "Ha!" at opposing infielders as he rounds the bases, after all, so who knows.

Either that, or Cynthia hasn't picked up the New York Post or read our celebrity gossip site yet. Once she does, someone's gonna have some explaining to do!
