"I'm engaged to him!" the actress writes, breaking the happy news via Twitter
“Him” is her musician boyfriend of six months, Snow Patrol band member Johnny McDaid, 37.
The Cougar Town star, who just celebrated her 50th birthday by flaunting her amazing bikini body on a vacation with McDaid in Turks and Caicos, recently spoke to PEOPLE about collaborating with the Northern Ireland native on her new film, Just Before I Go, which she directed.
“I’ve had a lot more support from him than him just being here tonight,” Cox told PEOPLE at the film’s premiere in April. “Snow Patrol wrote three original songs for this movie. I’m really fortunate. It’s amazing, all the musical things that he brought to it.”
Of his contributions, she added: “I couldn’t be happier. It really elevates the film in so many ways.”
Cox was previously married to actor David Arquette, and the two finalized their amicable divorce a year ago. They share custody of their 10-year-old daughter, Coco.
Best wishes to the bride- and groom-to-be!
