Jude Law's Lady -- One Hot Baby Mama

Jude Law is bound to have one good lookin' kid out of wedlock -- especially if the little sucker takes after its mother.

We got our hands on some photos of smokin' hot actress/model Samantha Burke -- the lady who's carrying Law's fourth bundle of joy.

You've already seen the pic we posted of Samantha with Jude's bun in the oven -- but wait'll you see these pics of Burke in a bikini!

As we first reported, her lawyer says she'll pop sometime this fall.
