However, being the rebel that she is, the 27-year-old had to put her own twist on things!

Not to be outdone, her assistant Jennifer Rosales attended the soirée as Ratchet Wilma!
LOLZ! These girls love to get themselves into trouble!
Luckily, the Barbados-native's friend Melissa Forde was able to capture the festivities on Instagram!
