Nicole Richie dropped by The Tonight Show with Jimmy Fallon on Monday and bragged about her experience joining Britney on stage during the “Freakshow” segment of Piece Of Me in Vegas.

Jealous!

She says of her stan card:

“Britney Spears came out when I was 15, and this was like the last time in my life that I was like a die-hard fan… that love never went away. Like, when I see Britney Spears I turn into my 15-year-old self. I can’t even handle it.”
