Natalie Portman's amazing year continues - her new movie has shot to the top of the box office.
Romantic comedy No Strings Attached opened with $20.3 million in its first weekend and took over the top of the box office from action film "The Green Hornet."
The success of "No Strings Attached" comes a week after pregnant Portman, who is engaged to her "Black Swan" choreographer and co-star Benjamin Millepied, picked up a Best Actress award at the Golden Globes.
The actress is the red-hot favorite to land the same honor at the Oscars.
