Celebrity date night. Times two!
Decked out in a hoodie, jeans and a Boston Red Sox baseball cap, the Oscar winner sported his 20/20 Experience World tour badge and carried his tickets as he made his way inside.
Also on hand was Amy Adams, who was accompanied by fiancé Darren Le Gallo. Like Damon, the American Hustle actress kept it casual in a blue top covered by a black blazer as well as a pair of cuffed jeans and leather boots.
Lily Collins, along with a few friends, also brought her adorable self to the big show.
One celeb who was not seen, however, was Timberlake's wife Jessica Biel. While there's no word if the singer's significant other was actually there or not, it certainly shouldn't be cause for alarm.
After all, when fans took to Twitter last Sunday to question why the brunette beauty did not attend the American Music Awards with Timberlake, she quickly replied, "I'm watching from home tonight. Calm down, Internet."
And so, we will do just that in this case as well.
