Elizabeth Olsen covers up in a wide-brimmed hat as she goes for a hike in the Hollywood Hills with her fiancé Robbie Arnett. Elizabeth Olsen got in some exercise Sunday with a hike up in the Hollywood Hills. The 31-year-old Avengers: Endgame star was joined for the trek amid the coronavirus pandemic by her fiancé Robbie Arnett, 28. She was dressed casually with a wide-brimmed straw had to block out the piercing sun. Elizabeth kept the rest of her ensemble casual and functional with a gray sweatshirt and gray and white seersucker pants. Robbie was dressed more casually in a navy high school volleyball hoodie with black sweatpants and a pink Texas baseball cap. The couple were on their own for the hike, but they both had bandanas tied around their necks to cover their faces if necessary. Los Angeles Mayor Eric Garcetti ordered anyone in Los Angeles to cover their face when visiting essential businesses earlier this week. Elizabeth and Robbie were fine, as a solitary walk outside doesn’t necessarily require a mask, but both were prepared if they ran into more people. The CDC is currently recommending Americans wear masks when in public, though it advises them to use cloth masks, like Elizabeth did, as opposed to medical-grade masks, which are in dangerously short supply at hospitals across the country.
