Report: Angelina Jolie and Jennifer Aniston at War; Playing Mind Games!

No, this isn't Turn Back the Clock week at The Hollywood Gossip. This is the real deal (according to Star): Jennifer Aniston and Angelina Jolie are at war.

The stakes: Probably non-existent.

The tactics: High-level mind games.

We are talking about dirty tricks, catty insults, 2 a.m. phone calls and the like. The kinds of things 12-year-olds do when they declare war on each other!

It's been almost five years since Brad Pitt split from Jennifer Aniston and took up with Mr. & Mrs. Smith costar Angelina Jolie, but Star Magazine two women involved in Hollywood's most famous love triangle cannot let their bitter rivalry go.

Tabloids have reported that Brad is running back to Jen - and whether that's true or not, it's clearly feeding the mutual dislike between the women of Brad.

The longtime feud has been refueled, in part, by both of the jealous, desperate women playing mind games with one another and refusing to back down.

Jen takes digs at Angie by flaunting her relationship with Brad's family while Angie relishes rubbing Jen's nose in the fact that she has six kids with Brad.

She might be having another without him, but no matter. The bottom line: "Jen and Angie despise each other and making each other squirm." Mmmkay.

Among the tricks Angelina Jolie employs? Finding out from designers what dress Jen wants to wear on the red carpet - then going for it herself. Burn!

Meanwhile, Jennifer Aniston makes late night calls to Brad when he’s in France, conveniently “forgetting” the time difference so she will wake Angelina.

As for Brad? He's "a terrible instigator" and even "eggs it on," according to reports. Hmm. Kind of like a rich man's movie star version of Brody Jenner.
