Los Angeles - Jennifer Aniston enrolled her and fiancé Justin Theroux into a "marriage boot camp".
The former Friends star is determined to make her union with the 41-year-old actor work so before they tie the knot, she got them to have an intense three-day therapy session in Santa Monica.
A source said: "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. 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."
'I find it very normal'
Jennifer, 43, also had to acknowledge the end of marriage to first husband Brad Pitt - with whom she split in 2005 - in order to move on and make this relationship a success.
The source added to Britain's Grazia magazine: "It was pretty tough going and they had to address all of their deepest fears and worries."
Jennifer - who has been dating Justin for around two years - has previously spoken about having the therapy say she found it very rewarding.
She said: "It's true that I spent some time regularly taking part in sessions with a psychiatrist. I find it very normal to lie on a couch every once in a while and to let your head be straightened out and your heart."
