At first she was happy and smiling, but suddenly things took a turn for the worse and something the person on the other end of the line said caused the tears to start flowing.
Sienna was spotted rubbing her fake bump and at times covering her mouth as her face distorted in sadness.
She was then pictured being comforted by one of her co-stars’ characters, who was clad in hospital scrubs.

Wearing little make-up, she teamed the pretty frock with a pair of black heels.
