Aniston, Theroux getting serious?

[1]

Hollywood actress Jennifer Aniston is reportedly smitten by actor Justin Theroux and the couple are taking the relationship seriously. The 42-year-old actress, who was previously married to Brad Pitt

and later dated Vince Vaughn and John Mayer, seems to have finally struck the cord with the 'Your Highness' star, reported Contactmusic.

"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," said a friend.

"They're together all the time. But they sneak around and do everything they can not to be photographed together. Jen doesn't like her relationships to go public before she's ready," the friend added.

The couple had earlier spent an weekend together, when Theroux had visited Aniston's home before meeting for a romantic lunch at the Beverly Hills hotel.

The former 'Friends' star later threw a small party at her house last Sunday with the actor and a few other close friends in attendance.
