Justin Theroux's girlfriend of 14 years is "heartbroken" over their split.

The 'Your Highness' actor - who has recently been romantically linked to Jennifer Aniston - moved out of the home he shared with Heidi Bivens last weekend and although she has refused to comment, friends claim she is devastated.

A representative for Heidi said: "Heidi and Justin have been together for 14 years. They met when she was 20 years old and he 24, and yes, she just moved out of their home last weekend. She has no comment."

Though the costume designer refused to be drawn on the reports, some of her pals say the news came as a shock.

A source told the New York Post newspaper: "Heidi is heartbroken. She was completely blindsided. She and Justin had been together for years, they had a home."

Friends of Justin, 39, say his relationship with Heidi was over long before he met Jennifer, 42, on the set of 'Wanderlust' last year.

A pal said: "Things were already over between him and Heidi before he got close to Jen."

Jennifer is said to be besotted with Justin and recently threw a party to introduce him to her closest friends.

A friend said: "Jen is totally into him. They have been hanging out for months.

"She wants to be with him all the time. She's diving in headfirst."
