Jennifer Aniston has become a loner, it has been claimed.

The 39-year-old actress, who is shooting new movie 'Traveling' in Vancouver, Canada, rarely socializes with her work colleagues and chooses to spend her spare time alone.

Courteney Cox has bought Jennifer Aniston a $12,000 Chanel bicycle. The actress bought her 'Friends' pal the expensive pushbike after she expressed an interest taking up cycling.

A source close to the star said: "Jennifer said she wanted to start bike riding because it's such good exercise. So Courteney sent her the new, ultra-chic Chanel bicycle."

Courteney Cox insists she and husband David Arquette are happier than ever. The former 'Friends' star, who married the actor in 1999, admits the couple have had their problems but have worked hard to overcome them.

Courteney said: "It was a matter of learning to live together and understand each other better. We're both intense and passionate people and we're both in a very chaotic and creative business with a lot of pressure to deal with. We figured out that it was a total waste of time to get angry with each other over stupid little issues."

Jennifer Aniston has been on a blind date with 'Entourage' Kevin Connolly. The 'Friends' star was reportedly set up with the 33-year-old actor by Tobey Maguire and his wife Jennifer Meyer.

Maguire and Meyer knew both stars were holidaying at Mexican resort Cabo San Lucas and suggested the pair met up.
