In the sweet pic, Moore and Timberlake were dressed in the trendiest pieces from the '90s. While it's hard not to notice their cute ensembles and Moore's platinum blond hair, their smiles were the clear focus of this throwback.
"Summer of 1999. Abercrombie tshirts and bucket hats," Moore, now 32, captioned it. "Opening for this guy and his band. Look at my nervous smile!"
Timberlake was also feeling the social media love on Tuesday, this time from Kevin Hart.
