We'll overlook the fact that she ended up sitting in first class anyway, because - generally - a lot of celebraddies wouldn't even notice a soldier waiting to board a plane, let alone give up their seat for them. Cynical souls would may say "She knew it'd get her some good PR", but how bad. Everyone's a winner here.
Someone by the name of Jemele Hill recounted the warm 'n fuzzy moment to the Today show, which occurred on a flight out of Detroit on Friday.
"When we were waiting to board, I saw her glance the soldier's way and then she said something to the person she was travelling with. Once we boarded, I saw she was in first class. I was upgraded to first class and she was a couple rows behind me. I think she must have said something to the flight attendant, because before we took off she had vacated her seat and the flight attendant brought the soldier to her seat... I just thought it was incredibly classy and thoughtful."
What's even classier is that she then proceeded to take selfies with the person she wound up sitting beside. Fair play, Ms Adams. Then again, it is quite hard to ignore someone you're sat beside while enclosed in a metal tube hurtling through the air at several thousand feet.
