The lovebirds have been together for 15 months and Theroux popped the question on Friday.

His representatives told People, "Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage."

Reps for Aniston, 43, have also confirmed the news.

The pair is rumoured to be tying the knot in Greece later this year.
