NEW YORK » Jennifer Aniston is ready to marry again: The actress is engaged to screenwriter and actor Justin Theroux.

Aniston’s rep, Stephen Huvane, confirmed the engagement Sunday night to The Associated Press. It was first reported by People.com.

Forty-one-year-old Theroux — 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 both appeared 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 Vince Vaughn and John Mayer.
