Smithsonian's giant panda cub Bao Bao celebrates 2nd birthday

Bao Bao is now two years old!

The giant panda cub, who currently lives at the National Zoo in Washington D.C., is kick-starting her big birthday bash.

The cub is very special -- and it's not just because Michelle Obama sent a special video message to her when she was first born. Bao Bao is one of only several hundred giant pandas alive today in captivity. There are less than 2,000 total worldwide. Although she's currently living in the United States, when she turns 4, Bao Bao will be sent back to live in China, her native country.

For her huge first birthday, the adorable cub was given a giant cake made of frozen fruits and veggies, while hundreds of museum-goers lined up to get a glimpse of the cub on her big day.

In preparation of the celebration, Bao Bao has been "tweeting" her excitement. Claiming:

You read that right! The cute cub may be getting a new brother or sister. Currently her mom, Mei Xiang, has been put on pregnancy watch and is showing typical signs that could mean she's expecting. Of course, Mei Xiang could just be in it for the air conditioning and extra food -- hey, we don't blame her.

Sure, the cute creature won't have a grand party like last year, but one thing remains the same: the giant frozen treat.

The more food, the merrier. Right?
