Given Johnny's not posted a tweet since February 1st (he wished Harry Styles a happy birthday) we can only assume the grand twitter announcement it wasn't his idea...

The Friends actress and her Snow Patrol beau shared the 'news' with their fans by each posting on Twitter "I'm engaged to him!" and "I'm engaged to her!" on their respective pages last night.

The lovebirds have only been dating for six months were first spotted out together in December when they attended Jennifer Aniston's holiday party in Los Angeles.

Suspicions were raised that things were moving rather fast when the couple's friend Ed Sheeran - who introduced them to one another - spilled the beans about them moving in together in April. Then there was the countless talk of weddings, then the massive engagement ring was carted around.

The 37-year-old and his band collaborated with the Cougar Town star on her directorial debut, Just Before I Go, and he opened up about his relationship with the actress for the first time at the film's premiere.

The Northern Irish guitarist gushed: "Courteney is the most completely confident person I've ever met - at everything. She gets music. She gets art. She gets the way a scene gets constructed, the way dialogue works. And she puts it all together in her mind and then explains it to the world and makes movies that make people laugh and cry, squirm and jump, all those things."

Courteney, who has just celebrated her 50th birthday (no wedding, as speculated), finalized her divorce from her ex-husband David Arquette, in May 2013 just before what would've been their 14th wedding anniversary.

According to reports (which shouldn't be believed given they were supposed to be getting tethered on her 50th birthday), they're planning a "three day Irish wedding."
