The newborn panda at Zoo Atlanta was named "Po" at a special ceremony Tuesday morning.
It's Chinese tradition to name a panda when he or she is 100 days old.
Born to Lun Lun on November 3, the cub was the only giant panda born in the U.S. in 2010.
The baby panda's name is a tribute to the lead character from the "Kung Fu Panda" film series. "Kung Fu Panda 2" will be released on May 26.
The cub's name was announced by actor Jack Black, who voices the iconic character of Po in the DreamWorks Animation films.
"In addition to the name ceremony, we're excited to announce Po took his first two steps Monday on his own," said Rebecca Snyder, the curator of mammals at Zoo Atlanta. "He's learning to stand, too." she said.
The baby panda lives in the Giant Panda Conservation Center, and spends most of his time with his 13-year-old mother. His father, Yang Yang, also lives at the zoo.
Tuesday's announcement is the beginning of an alliance between Zoo Atlanta and DreamWorks Animation.
"Our organizations share a commitment to giant panda conservation, particularly at the Chengdu Research Base of Giant Breeding (in China)," said Raymond King, president and CEO of Zoo Atlanta.
Giant pandas are endangered, with fewer than 1,600 believed to remain in the wild.
