Jennifer Aniston's new beau extremely temperamental

Jennifer Aniston will dump boyfriend Justin Theroux when he starts to show is true colors sources say.

“He’s one of the most moody people I know,” a source said.

“He’s extremely temperamental. It will collapse like a house of cards once Jen finds out who Justin really is.”

Meanwhile, Jen has reportedly moved Justin into her Los Angeles home.

The couple recently started dating after meeting on the set of Wanderlust last year and are so serious about each other that the actress is believed to have asked Justin who has an apartment in New York and usually stays at the luxurious Chateau Marmont when he is in Hollywood to move in to her Beverly Hills pad.

“He’s living at her place in L.A.! And she’s introducing him as her boyfriend,” a source told Us Weekly.
