Jessie J Talks Katy Perry Duet...
She responded to a fan about the possibility of a collaboration between her and Katy, simply saying: "No its not true."
Still, Jessie enjoyed a busy weekend, visiting LA theme park Six Flags, and enjoying every minute of it. She tweeted:
"Just left six flags! WOW one of the best days ever! 15 roller coasters and 3 fright mazes... I screamed a lot :\
"I laughed so much today my ribs hurt. Great times with great people!"
Sounds like she's having a blast in the States! BS
