The 'Price Tag' singer has revealed she has a crush on Rihanna and is obsessed with Katy Perry.
Jessie, who has previously admitting to being bisexual, also said she had her eyes on American male model and actor Tyson Beckford.
She told Fabulous magazine: "I don't have a boyfriend. I've got a crush on Rihanna. And Tyson Beckford - I wouldn't kick him out of bed.
"And I'm slightly obsessed with Katy Perry. I'm so gutted I won't be singing I Kissed A Girl with her on tour."
Jessie was due to support Katy on the latest UK leg of her California Dreams world tour but was forced to pull out because of her broken foot.
Meanwhile, the singer kicked off her own UK Heartbeat tour in Birmingham last night (18th October) and you can see photos from the O2 Academy here.
