Jennifer Grey is returning to TV: The "Red Oaks" actress is set to appear on "Grey's Anatomy" in a mysterious midseason arc.

TVLine has the scoop that Grey will be joining the long-running medical drama for an unspecified stint sometime during the second half of season 15. ABC confirmed the news, though they declined to provide any additional details about Grey's character or the length of her arc.

According to TVLine, one possibility is that Grey could be playing the estranged mother of Camilla Luddington's character, Jo. Luddington previously told the site that Jo's mysterious, as-yet-unseen parents would be making an appearance on the show sometime this season.

Grey's role on "Grey's" (sheesh, this is getting confusing) will mark the second time someone from her family has appeared on the series. Her father, actor Joel Grey, previously starred in a season six episode as an Alzheimer's patient and former teacher of Izzie's (Katherine Heigl), who Izzie helps spring from a nursing home. Here's hoping his daughter's part is equally juicy.

"Grey's Anatomy" will return from its midseason hiatus on January 17. Keep your eyes peeled for a real-life Grey to pop up soon.
