For a show titled “Two and a Half Men,” there are plenty of woman that come and go. Although it revolves around the escapades of Charlie, his brother Alan and Alan’s growing son Jake, their worlds revolves around women. It’s the driving factor of almost every episode. Their relationships with women define who they are as characters. And despite the slight irony in the title, the show continues to add more and more stunning female characters for the three, or two and a half rather, men to lust over.

Paul Marshall will bring a little romance and a major surprise to “Two and a Half Men” next month. Marshall (“Nip/Tuck”) will appear on two episodes as a love interest for Alan with a surprising past, TVLine reports. She’ll make her debut on Dec. 5.

Diane Farr from “Rescue Me” is also set to appear during Marshall’s second episode on Dec. 12 as Rachel, a woman with close ties to Paula who will help shed light on her intriguing past.

But the influx of ladies doesn’t stop there. Aly Michalka has been cast as Brooke, a recurring character who will act as a love interest to Amber Tamblyn’s Jenny. According to TVLine, she’ll star in at least two episode this season, the first of which will air on Dec. 12.
