But The People For Ethical Treatment of Animals is upset about their choice of  entertainment and are planning on contacting the newlyweds to express their  grievances.

"We know that Nicole is sympathetic to the  plight of animals in the circus and is opposed to the way in which baby  elephants are slammed to the ground and gouged with steel-tipped bullhooks  in order to train them for circuses such as Ringling Bros," PETA said in a  statement.
