For the upcoming April 27th episode of The Big Bang Theory, "The Vegas Renormalization," in which Leonard and Raj take Wolowitz to Las Vegas to get over a breakup, we previously hinted there would be hookers involved.

Now we have the name and actress behind one of the prostitutes.  The beautiful Prison Break alum Jodi Lyn O'Keefe will guest star as Mikayl according to TV Guide.

As for Sheldon, well, as we already told you, he'll be stuck having a sleepover with Penny after locking himself out of his apartment and his potential "weekend of dreams."
