Ross is the son of the late mountaineer Arne Næss Jr. He has been married to singer-songwriter Ashlee Simpson since 2014, with whom he has one daughter.
Ross was born Evan Olav Næss in Greenwich, Connecticut to businessman and mountaineer Arne Næss Jr. His father was of German and Norwegian descent and his mother is African-American.
Ashlee Simpson cut a stylish figure in cat-eye sunglasses when she stepped out in Thursday, her one-year-old daughter Jagger in her arms.
Accompanying them was her husband Evan Ross, who'd popped a chic top hat on his head, matching his voluminous sweater.
The pair, who popped by Teddy's at the Roosevelt Hotel late Monday evening, stayed close as they stepped out of the nightclub around early Tuesday morning, with Simpson, 28, looking chic in a floor-length flowered maxi dress, her blonde hair worn loose around her shoulders.

Nearly a year after Ashlee Simpson and Evan Ross tied the knot in August 2014, the Hunger Games actor is looking back on their big day.
