She's really working out right up until her due date!

Mila Kunis headed to her daily yoga class this morning in Sherman Oaks, and the actress better be careful her water doesn't break right in the middle of downward dog! After all, the brunette beauty is set to give birth any day now, and by the looks of that baby bump, it's going to happen sooner rather than later!

The Black Swan star and fiancé Ashton Kutcher are undoubtedly thrilled to welcome their firstborn, and apparently the Two and a Half Men actor is already a doting dad. "Ashton is not letting Mila out of his sight. They are spending every moment together. He can't wait," a source told E! News. "Mila is so excited about the baby. She's not nervous at all. She's been really calm and chill about it all," the source added.

Somewhere Demi Moore is crying!
