Jennifer Aniston to marry writer Justin Theroux

• Friends star to marry again seven years after divorce from Brad Pitt

• Aniston’s love life has been subject of tabloid scrutiny

Aniston’s spokesman Stephen Huvane confirmed the engagement after it was first reported by People.com.

Theroux, 41 - whose screenwriting credits include Tropic Thunder, Iron Man 2 and Rock Of Ages - popped the question on Friday, which was also his birthday.

The two appeared together in the comedy Wanderlust, also starring Paul Rudd, earlier this year.

This will be 43-year-old Aniston’s second marriage and Theroux’s first.

Her union with Brad Pitt from 2000 to 2005 - and their subsequent divorce - became rich material for the tabloids.

After her marriage ended, she was in high-profile relationships with actor Vince Vaughn and musician John Mayer.
