Jessica Alba's baby human Haven was playing with her other baby, doggy Sid!
Jessica's husband Cash Warren tweeted the pic (above).
They're just so CUTE!!!
Seriously, put any baby and a dog in a room and you've got guaranteed cuteness.
But put a celebrity baby and a little dog in the same room, and you're playing with fire.
Serious cuteness overload territory.
Look at them, they're about the same size! It's so adorbz.
