Angelina Jolie is telling a "select group of people" she is pregnant, it has been claimed.

The Hollywood star and her partner Brad Pitt already raise six children together. There has been intense speculation they might be planning to add to their family, and it's now been alleged Angelina is already with child.

"She's almost three months along," a source told the American edition of OK! magazine. "It's not something she wants to officially announce but she's at a point where she is telling a select group of people."

Another insider claimed the actress is enjoying being pregnant even though she is suffering some adverse effects.

"Angelina is really savouring every moment. She's having a tough time with morning sickness but says it's all worth it," the person added.

Despite the report, Angelina showed no signs of pregnancy at the Golden Globe Awards on Sunday night. She attended with Brad and wore a stunning cream gown which hugged her figure including her flat belly.

The star has been promoting her directorial debut In the Land of Blood and Honey recently and has discussed her future family plans several times.

"Nothing planned at the moment, but we just don't know," she said last year. "I could end up pregnant."
