Angelina Jolie has accused Jennifer Aniston of embarking on a "sneaky" relationship with Brad Pitt's mother.

The Tomb Raider star is reportedly furious Pitt's mother, Jane, has invited his ex-wife Aniston - who has been estranged from her own mother, actress Nancy Dow, for nine years - to spend the Thanksgiving holiday (22Nov07) at her home in Missouri.

And Jolie has even threatened to disown Jane if she continues her friendship with Aniston. Tiffany Law, a pal of the Friends star, tells Britain's Star Magazine, "Jen sees no reason to stop (contact with Jane). They speak on the phone at least once a month and exchange cards and e-mails. But, apparently, it makes Ange's skin crawl.

"Ange has pulled no punches, and has made it clear to Brad that there will be no family harmony while Jane keeps up her friendship (with Aniston). But Brad has told Ange that what his mother does in her free time is her own business."

Aniston and Pitt divorced in 2005 after five years of marriage, but the actress has remained close to her former mother-in-law since their split. (LR&PAW/WNWCMAC/LJ)
