Angelina Jolie and Brad Pitt 'expecting baby'

The actress, 35, and her partner Pitt, 48, already raise six children together, but are expecting their seventh child this year, according to OK! magazine.

The star has already started decorating a room for the new arrival, according to the source.

"Angelina has cleared out her bedroom and redone it in white. She wants it to have a Zen-like feeling because she believes in the mind-body connection and wants her mind at peace," the source said.

Jolie and Pitt fully dressed their part as a glamorous Hollywood power couple at Sunday night's Golden Globe Awards: She in a body-hugging white strapless gown with a flash of red at the bustline by Atelier Versace that matched perfectly her lips and handbag, and he in a classic, bow-tie tuxedo by Salvatore Ferragamo.

"A Separation" by Iranian filmmaker Asghar Farhadi won the best foreign language film at the Golden Globe awards on Sunday, beating rivals from China, Spain and Belgium, as well as Angelina Jolie's directorial debut, "In the Land of Milk and Honey".
