Actress Mila Kunis, who is expecting her first child with Ashton Kutcher, has reportedly been suffering from morning sickness and is very tired.

The 30-year-old is struggling with nausea, and her fiance is lovingly by her side to help her throughout.

"Mila's been suffering from morning sickness and is feeling exhausted, but she says Ashton has been her rock. He's been cooking her breakfast in bed. He's even hired a masseuse to give her daily massages and, at night, he rests his head beside her bump and talks to the baby,` contactmusic.com quoted a source as saying.
