For her roommate Camila Mendes, she's taken complete advantage of that.
Camila took to her Instagram story to share with her fans that she was up to no good. She was on a mission to steal Lili's Girl Scout cookies. But, she had to be careful because Lili was home.
Camila explained that she had to be "extra sneaky this time," and she was "already on the naughty list." So she's definitely done this before.
While Camila obviously thought she was successful, snacking on the Thin Mints in front of all her fans, she had no idea that Lili was behind her, filming her in action.
Just see the look on Camila's face when she turns to see Lili filming her.
God we want to be their friend.
