First up, she made the rookie error (or totally genius decision) of wearing her iconic Betty pony tail.
Posting a fantastic string of photos on her Instagram story, Lili explained how a worker at the DMV recognised her.
"Girl at the DMV says - 'Do you watch the show Riverdale? You look just like the girl on there."
In another snap, she captioned, "I said, 'I do?? Omg thank you so much!'" Lol.
But her third pic was the best, captioned, "jk I said 'yup that's me,'" and TBH if we were her we'd be rolling in the glory of being Betty as well.
