The Friends actress started dating the Snow Patrol rocker in November last year and the loved up couple were recently spotted holidaying at Amanyara in Turks and Caicos celebrating Cox's 50th birthday.
From the looks of this engagement announcement selfie (check those tans) we're guessing Johnny popped the question while on holiday... a beach proposal, perhaps?
The couple met last year after being introduced by British singer Ed Sheeran (yes, really) and have been pretty inseparable ever since.
When they do eventually tie the knot, it will be Cox's second marriage. She was previously married to actor David Arquette but the couple finalised their divorce a year ago.
With a new man on the scene and a wedding to plan, this is definitely happy-making news. The question is, will she do the big wedding thing again or keep it low-key? AND will she say "I do" before her BFF Jennifer Aniston does?
