They're princesses of pop from opposite sides of the Atlantic, and tonight Katy Perry and Jessie J rocked correspondingly opposing looks for the MTV Europe Music Awards in Belfast.
Katy, 27, went for a 'Pink Lady' look, teaming her unseasonably summery dress with a diamante studded baby pink jacket and heeled trainers.
English pop star Jessie on the other hand went for an unusually feminine strapless gown- albeit in eye-catching leopard print.
Katy posed alongside designer Jeremy Scott, who rocked an equally outlandish ensemble and a similar rolled quiff hairstyle.
Jessi's curly bobbed 'do and yellow leopard-print Dolce & Gabbana dress were quite a departure from her usual bodysuits and shorts.
The 23-year-old kept her makeup bold as ever however, with smokey eyes and scarlet lipstick.
The Do It Like A Dude star is up for two MTV EMAs, including Best New Artist, Best Push and Best UK & Ireland Artist.
