This one takes the cake.

Joan Rivers had a not-so-sweet sweet-tooth encounter when she was photographed Friday dashing out of a Los Angeles party covered in what looks like icing and cake.

The 80-year-old Fashion Police host was attending the QVC Red Carpet Style bash at the Four Seasons, in the online retailer’s run-up to this Sunday’s big Oscar blowout.

Dressed in a black lace overlay and trousers, the comedian was all smiles working the red carpet as she entered the party, but, afterward, stormed out slathered in icing as she flailed at shutterbugs while making a beeline for her car.

So who was the culprit?

Turns out, the debacle was an elaborate publicity stunt orchestrated by none other than … Miss Piggy.

The diva Muppet is set to launch her own line of products on QVC, and – in a gag video from the event that popped up on Saturday – Miss Piggy and Rivers get into a verbal melee before the comedian is shoved into a towering cake.

The feisty Muppet also taunted Rivers on Twitter, writing: “If @Joan_Rivers can do a line on @QVC, I can do it better! How do you like them apples, Joannie!?”

Then again, Rivers has had quite a mouthful of pastry in the past: For her birthday last year, the funnylady took a cake to the face when Fergie stopped by Fashion Police and offered up a memorable food fight.

Talk about just desserts.
