Whata ya know... Anna Nicole takes every pill in her cabinet but the Ortho Tri-Cyclen....

Anna Nicole Smith is 100% pregnant, sources tell PerezHilton.com. And, contrary to published reports, the buxom blonde is not on the outs with the baby's alleged father, entertainment journalist and photographer Larry Birkhead, pictured above with Smith in an old photo.

In fact, things between the former Playboy Playmate and the journo are definitely "on" and the two are currently vacationing together in Myrtle Beach, South Carolina, PerezHilton.com has learned.
