Angelina Jolie craving chips dipped in milkshake

Hollywood superstar Angelina Jolie is starting to get the unusual food cravings experienced by many expectant mothers, it has been claimed.

The actress, who is widely believed to be expecting twins with partner Brad Pitt - though she is yet to confirm the speculation  - has reportedly been gorging on fatty snacks including burgers, chips, ice cream and milkshakes from a popular US hamburger chain.

And she even has them together - dipping her chips in her milkshake.

"She's really not watching her carb intake or anything she's eating," says a source close to the 32-year-old actress

"She has In-N-Out French fries dipped in milkshake and hot sauce. Gross – but she is pregnant!"

The 'Tomb Raider' star showed off her baby bump at The Spirit Awards last weekend with partner Brad Pitt, 43.

The couple are already parents to daughter Shiloh, 20 months, and adopted children Maddox, 6, Pax Thien, 4, and Zahara, 3.
