Is This Gwyneth Paltrow's (Tasty) Diss Back at Martha Stewart?

Goop founder posts a recipe titled "Jailbird Cake"

This just may be the most delicious feud in Hollywood history.

It seems like Gwyneth Paltrow has decided to fire back at Martha Stewart, and you know what they say—revenge is a dish best served cold with a garnish of chocolate shavings.

The Goop founder posted a tasty recipe on her website that's been dubbed "Jailbird Cake," which we can only assume is a cleverly disguised diss at her domestic rival, who (in case you've forgotten) served some time behind bars in 2004 for insider trading.

E! News has reached out for comment.

Gwyneth's sweet shade comes after being the target of similar treatment.

In the November issue of Martha Stewart Living, the 73-year-old businesswoman took an epic dig at the Oscar-winning actress, mocking the famous "Conscious Uncoupling" statement that Paltrow and ex Chris Martin released when they announced the end of their marriage in March. 

The mag's spread, which is hardly a subtle slam, is poignantly titled "Conscious Coupling" and focuses on exceptional food pairings, spotlighting Thanksgiving pies which boast the "perfect marriage of crust and filling."

"The folks at Goop know how to have some fun, too," a source close to Paltrow tells People magazine. "If Martha served up the appetizer, the Jailbird Cake is just desserts."

If these two would like to continue their food feud, we'd like to suggest that they come up with some cocktails next? These sweets are making us parched.
