It tells the tale of three couples' intertwining love stories and unfolds in in Rome, Paris, and New York.
Mila only recently confirmed she is expecting a baby with her former That 70s Show co-star Ashton. She has not revealed her due date or the gender of the forthcoming arrival, but has said she and Ashton have already chosen a name for the little one.

Mila, who is fluent in Russian thanks to her Ukrainian upbringing, said Ashton is also learning the language so they can speak to their new arrival in the East Slavic language.
"He's been taking classes for like six months now," said Mila during an appearance on the Ellen DeGeneres Show. "He does it twice a week, a woman comes to the house and gives him lessons."
Mila is hoping to have a natural labour, without an epidural.
"I'm going to do it as natural as I can, unless there's an emergency," she said. "I know, I'm crazy, but I did this to myself I might as well do it right."
