They're one of the most elusive couples in Hollywood, but even Ruth Negga and Dominic Cooper break their own rules every now and then.

The Irish actress (33) who previously featured on Love/Hate, has been dating British actor Cooper (38) for the last six years and the couple live together in London.

And as one of the most private couples in showbiz (both refuse to comment on their relationship in interviews), they were the subject of split rumours earlier this year by a tabloid magazine.

But the talented pair proved they're in love as ever as they walked the red carpet together for the first time at the premiere of Warcraft. They first met in 2009 while working together in a stage adaptation of Phèdre with Helen Mirren.

Since then, both of their careers have steadily soared as they prepare for their busiest 12 months yet. They pair have wrapped filming for their AMC tv show Preacher, their third project together in recent years.

Ruth's latest film Loving premiered at the Cannes Film Festival and she's already being tipped for a Best Actress Oscar nod for her role in the critically acclaimed film.

She has also featured in 12 Years A Slave, World War Z and had a recurring role on Marvel's Agents of S.H.I.E.L.D.

As for any signs of a sparkler, Ruth wore a dramatic metal ring presumably to throw off speculation about their relationship status.
