The singer told the Daily Star:
"I'm obsessed with Britney's Fantasy perfume. I bought it when I was writing the album so now I always wear it for good luck before every show. The bottles are so small and I use so much I'm always buying it."
We know how Jessie can solve that problem. Come out with her own scent!
It'll happen, just watch.
