Well this is certainly a strange date night!
How do we know?
You'd think they wanted to dance to the music together!
Ch-ch-check out their videos (below)!!!!
Oh hai, Amanda Seyfried! What nice panties you have!
Even though Mandy went sans pants in New York the other day, this is actually more clothes than she's used to wearing!
After all, she took it ALL off in order to play porn starlet Linda Lovelace earlier this year in the R rated biopic Lovelace! Amanda had to drop trou this week while filming her upcoming flick While We're Young.
We're assuming the script called for Amanda's character to show some skin during this exterior scene. Or maybe they were wrapped for the day and Manda just wanted to slip into something more comfortable?
Whatever the case may be, we LOVEZ your orange knickers, Miss Seyfried! And we bet Justin Long would dig 'em too. So long as they eventually ended up hitting the floor…
