The `This Means War` actress is currently pregnant with her third child and has been waking in the night with desperate urges for strange foods.
A source told Closer magazine: "Reese has been waking up at 3am and cravingseaweed smoothies, pickles and peanut butter all together, plus chicken wings smothered in barbecue sauce."
And it isn`t only at night when the 36-year-old actress - who also has children Ava, 12, and Deacon, eight, from her marriage to Ryan Phillippe - has been craving particular foodstuffs, she also fills up on fruit and yoghurt in the day time.
The source added: "In the day, she only wants bananas and strawberry yoghurt - by the litre. She usually sticks to a healthy diet so she`s hoping the cravings stop soon."
