At the Vanity Fair and FX’s pre-Emmys celebration at the Century City eatery Craft in Los Angeles, Rhys was photographed standing in front of Russell, giving her hair-do a final adjustment.
Rhys, 42, wore a navy blue jacket and dark jeans while Russell, 41, wore a long, tiered red dress with spaghetti straps.
Both Rhys and Russell have received Emmy nominations for the final season of their hit Cold War spy drama, The Americans.
Back in June, Rhys told PEOPLE that one of they keys to making his real-life relationship with Russell work while they are also spending almost every day together on set together at The Americans was making sure they both got alone time.
He also expressed his gratitude for Russell’s positive attitude. “She has the patience of a saint, so that helps,” he said. “That is basically it.”
Well, Rhys admitted there was one other tool that really helped.

“And alcohol,” Rhys added with a laugh. “The great leveled, the great equalizer. Everything is so much better after a good, solid half bottle of red wine!”
