Actress Jennifer Aniston and her fiance Justin Theroux have reportedly enrolled themselves into a marriage boot camp for a fresh start. Aniston, 43, and Theroux, 41, registered themselves for an intense three-day therapy session in Santa Monica. "Jennifer and Justin are super excited about their big day, but she thought it would be a good idea to start married life rid of any problems. Justin seems to be as much a believer in the therapy as Jennifer is," contactmusic.com quoted a source as saying.

"On arrival, they had to hand over their mobile phones and undertake counselling, couple massages and screaming therapy - where you howl your feelings out at the top of your voice," the source added.

Aniston was married to Brad Pitt and they split in 2005.
