Jennifer Lopes showed off her lovely locks in New York City this morning. The Monster-In-Law star stopped by Good Morning America to raise awareness about pertussis, a potentially fatal disease better known as whooping cough.

Whooping cough cases were virtually unheard of in the US due to the creation of a vaccine but lately Hispanic babies have been hard hit. The immunization wears off after time so J-Lo was urging adults to get a booster shot to prevent spreading the disease to children.
