Not only did she completely break down in tears after receiving a video message from Mel B during an interview with 2DayFM in Australia last month, but she memorised each popstar's autograph when she was 10-years-old. And can still do them all by heart.
The American actress was on Jimmy Kimmel Live promoting her latest movie, The Amazing Spider-Man 2, and proved that she can still sign on behalf of Sporty, Scary, Baby, Ginger and Posh.
Watch this, there's nothing like being put to the test on live TV but it's cool - she's seriously good...
And FYI did you know that the 25-year-old redhead's real name is actually Emily? But her love of the Spice Girls cued her changing it to Emma, as she always wanted to be Baby Spice. The star confirmed that: "So I'm Baby Spice for life!"
Ok, so Stone has their autographs down to a tee and she's spoken (via video) to Mel B but surely it's time she met all five girls in person.
A fan this loyal will have definitely had every lyric and dance routine perfected - we reckon she collected every Spice Girls card she could get her hands on too.
LOVE EMMA STONE'S STYLE? Check out this gallery all about the girl because she's got heaps of looks to steal...
