Who's the daddy? Is it a boy or girl?
The National Zoo in Washington will answer those questions Thursday morning when it announces the gender and paternity of a giant panda cub that was born last month.
"Stay tuned! We're going to announce the sex and paternity of the panda cub tomorrow around 9 a.m.! #cubwatch," the zoo tweeted Wednesday.
The news was greeted by joyous tweets from fans of Washington's celebrity panda, Mei Xiang.
