An old time favorite from "Two and a Half Men" will make a guest appearance on the popular sitcom in Thursday's all-new episode.

Rose, the woman who famously stalked former "Two and a Half Men" star Charlie Sheen and then Walden, will return to the show in the upcoming holiday-themed episode titled "Clockwise In Back Hole Until Tight." In a press release, CBS confirmed that actress Melanie Lynskey will reprise her role as Rose for at least one more episode before the series ends next year, reports Carter Matt.

A preview of the next episode published by Yahoo! also reveals that Walden and Alan will go to extremes to convince their foster son Louis that Santa Claus is real.

"Walden and Alan are determined to convince Louis that Santa Claus is real," the synopsis states according to AceShowBiz.com.

In a recent interview on "The Ellen DeGeneres Show," current series star Ashton Kutcher dropped hints about Sheen returning for the series finale next year when DeGeneres asked if they had shot the series finale yet.

"No, we haven't shot it, but I got pitched yesterday what the story is going to be," Kutcher responded. "... It's uh, I don't know if I'm allowed to talk about it. But I'm scared ... Yeah, I'm a little terrified."

He then warned her that if police sirens go off at the Warner Brothers studio where they film the show, then "come save me."

However, when DeGeneres pressed him about whether Sheen is coming back, the actor responded with an awkward denial.

"I didn't say that," Kutcher said. "I'm not saying that. Did I say that?"

Season 12, Episode 8 of "Two and a Half Men," "Clockwise In Back Hole Until Tight," airs on Thursday, Dec. 18 on CBS.
