Blu Cantrell
The ex-girlfriend of Beyoncé’s husband Jay-Z, Blu Cantrell may or may not still be sour over their failed relationship. Rumor has it that Jigga dumped the songstress for the then Destiny’s Child singer and the rest is history. In 2012 Blu coyly remarked on Twitter that she “loved” the name Blue Ivy that the Carters picked out for their baby girl.
