The realty TV star will be making a guest appearance on CBS’ The Young and the Restless on Thursday. In the recent season premiere of RHOBH, Davidson presented Girardi with the ultimate gift during her 45th birthday celebration: an opportunity to make a guest appearance on Y&R! In the upcoming episode, Girardi, who will play Farrah Dubose — a no-nonsense business women — visits Genoa City, where she’ll cross paths with fellow RHOBH star Eileen Davidson, who plays Ashley Abbott on Y&R. In the clip, Davidson — who is just trying to enjoy a simple cup of joe — accidentally runs into Girardi … literally. After Davidson’s hot coffee spills all over Girardi’s white, custom couture blazer, the two exchange some not-so-nice words, but eventually go their separate ways. Girardi’s episode of The Young and the Restless airs Thursday, Dec. 15 at 12:30 p.m. ET on CBS.
