Trisha Yearwood is among the stars who have pulled out of appearances at Orlando Florida's Sea World over the treatment of the park's killer whales.

She follows in the footsteps of Willie Nelson, Barenaked Ladies and Heart, who have cancelled appearances after allegations of mistreatment of the whales was exposed in the CNN documentary Blackfish.

According to TMZ, Trisha hasn't seen the documentary but has heard enough about it to make her want to pull out of the February event.
