It has just been announced that Courtney Thorne-Smith is going to guest star on the CBS show Two And A Half Men.

In a multi-episode arc, she will play Lindsay, a girlfriend for Alan (Jon Cryer) who is a deeply neurotic, recently divorced mother of a rotten 16-year-old boy.

Thorne-Smith, who spent eight seasons on ABC’s “According to Jim,” recently starred in the Lifetime Movie Network film “Sorority Wars.”

Were the producers preparing for Charlie Sheen possibly leaving the show for a while (for rehab or jail time?) by juicing up Cryer’s storyline?
