Brad Pitt is upset his mother Jane is still in touch with his ex-wife Jennifer Aniston, according to his younger brother Doug. Doug, 39, tells British magazine Star that Jane speaks to the star on the phone once a week - nearly 18 months after the couple's shock split in January 2005.

Although Pitt has swiftly moved on to a new relationship with Angelina Jolie and is now a father to adopted children Maddox and Zahara Marley, Jane is yet to cut off her former daughter-in-law Aniston.

Doug says, "Brad is not happy about Mom talking to Jennifer. He feels that Mom should move on now, and cut the link that was there. But she is in a difficult position - she has great affection for Jennifer - born out of the fact Brad once loved her and did marry her."

Pitt and Jolie are expecting their first biological child together this month.
