This is a far cry from her sexy airport look at Heathrow a couple months ago.
She was seen coming into LAX from Paris on Wednesday looking crazy casual. If it weren't for her super cute black-rimmed Prada specs, we'd think she was just strictly PJing it all the way.
Wearing some baggy gray sweat pants, a Trapstar x Hitman skull sweatshirt, and Timberland boots, RiRi was all about keeping things low-key during her plane ride.
We can't blame her though! It's always best to b e comfortable on a long flight!
