Future is gonna be piiiiissed.
As we've reported, Ciara and Future are in a nasty custody battle over their son. Future's already said he's not thrilled about public photos of Russell with his kid ... so, this feels like throwing fuel on a fire.
In the couple's defense, they didn't release the pics -- the Dodgers tweeted them Tuesday.
If nothing else ... it looks like baby Future had a great day, and Ciara got next year's Christmas card?
