Liev Schreiber and Naomi Watts do enjoy stepping out to an awards show – but it’s not exactly a romantic evening away from the kids.

“It’s not really what I would call a date night. It’s a good room of people,” Watts, 44, told PEOPLE Sunday on the red carpet at the Screen Actors Guild Awards, where she was a nominee for outstanding female lead actor for her role in the film The Impossible.

“It’s great seeing my wife dressed up,” Schreiber, 45, said, after being asked about how fabulous she looked, sparkling in a strapless gown by Marchesa, set off with Christian Louboutin heels, a Salvatore Ferragamo clutch and Fabergé earrings.

While the pair – who have two sons, Sasha, 5½, and Kai, 4 – looked luminous together on the red carpet, the time it takes to get ready is long for her and short for him.

“Two hours, that’s all. It’s too much time otherwise,” Watts, an Academy Award nominee, said of her routine, which includes a certain beauty treatment.

“I always do a nice scrub on my face with a Clarisonic and I drink two liters of water and that helps the skin,” she adds.

Meanwhile, Schreiber jokes, “I wait. I wait, play with the kids and I time it. Fifteen minutes before it’s time to go I start [to get ready].”
