Bethenny Frankel and Jason Hoppy -- Guess Whose Face Tells the Real Story

Bethenny Frankel and estranged hubby Jason Hoppy buried the hatchet -- temporarily -- to celebrate their daughter Bryn's birthday.

They were strolling the street in NYC, looking happy, but snapshots can be deceiving.

As TMZ first reported, Frankel filed for divorce in January 2013, but they have been in a mega- fight over money and custody issues ever since. Just last month, Bethenny was ordered to fork over $100k to Hoppy's attorneys ... and still there is no deal done.

Maybe the divorce will be settled before Bryn's next birthday.
