Well the cat’s out of the bag… I can finally say that another childhood dream has come true! Growing up, I adored Princess Jasmine from Aladdin. Having a Disney role model to look up to as a young teen, who was strong, smart, witty and true to herself, and happened to be diverse, was so inspiring! Now to play her is such an honour. This casting means especially so much to me because of all you lovelies who wanted me to play this role from when I first started on Galavant! Thank you for believing in me! ? I am so grateful for such an amazing opportunity and so thankful to ABC, Veronica at casting, Adam Horowitz, Edward Kitsis and the Once Upon A Time family! Storybrooke! Here I come!
