Modern Family's Valentine's Day episode will see the return of Phil and Claire's sexy alter egos, Clive Bixby and his mistress, Juliana. Once again, they start out their night at a hotel, "but things go awry and there is a dramatic turn of events," teases Julie Bowen (Claire).

Gloria (Sofia Vergara) gets the OK from her doctor to resume sex after giving birth, which sends her hormones into overdrive, and Mitch and Cam (Eric Stonestreet and Jesse Tyler Ferguson) experience their version of The Hangover.

"We get really wasted the night before and wake up without fully remembering what happened," says Ferguson. "As we go through our house, we get clues and discover our cat has been dyed pink." Plus, Cam and Mitch debut their own versions of Clive and Juliana.
