Katherine Schwarzenegger and Chris Pratt are savoring those last moments together before their baby is born! The couple held hands and beamed with joy as they left their lunch date. Katherine rocked a long, aztec-patterned coat that covered her baby bump. Although at one point, she did open up her jacket revealing her big baby bump in a black tank top and leggings. She completed the outfit with a pair of sunglasses, long necklace and a blue purse.
