As we all wait to see if Tian Tian will give birth to the UK's first giant panda cub in Scotland - a zoo in America's celebrating their new arrival.
Keepers at the Smithsonian National Zoo in Washington DC say giant panda Mei Xiang gave birth last night.
The cub is the second to be born at the zoo.
The zoo revealed the news by tweeting: "WE HAVE A CUB!!"
The zoo has been on round-the-clock panda watch since August, when Mei Xiang began showing signs of pregnancy.
