Looking simply stunning on the red carpet, the newly engaged "Avengers" star donned a strapless little black dress, matching heels, and pearls while her dashing co-star sported a gray suit with a red button on the lapel.
Though she's currently busy with film festival season, the 28-year-old actress knows that you can't wait around for the perfect time to plan these things.
Speaking about her engagement in an interview with "ET Canada" Scarlet shares, "My friend was like 'congrats on timing.' Things work out the way they do. Maybe it's better just to get it out the way."
