After a paternity mystery, the father was finally revealed Thursday. We're not talking about some famous Hollywood couple however, but a couple of pandas at the Smithsonian National Zoo in Washington.
It all started a few months ago when panda mom Mei Xiang was artificially inseminated with sperm from two different male pandas - Tian Tian, from the same zoo, and Gao Gao, from the San Diego Zoo.
The Giant pandas, who are endangered animals, are notorious for having difficulty breeding and producing cubs. Therefore, the zoo thought it was better to double Mei Xiang's chances in getting pregnant.
Well, it turns out that Tian Tian is father. The cub's sex was also revealed - it's a girl.
"It's got a fat little belly," National Zoo senior curator Brandie Smith said, to the Associated Press, about the newborn cub. "It's very active, very vocal."
She added that the zoo is finally really celebrating the cub's birth, as the 10-day mark is critical for the survival of a panda, at which stage zoo keepers feel more confident about the cub's future.
The cub will stay with her mom for two years, after which she will be weaned and live at the zoo for four years, before being sent to China.
China owns the pandas at the Smithsonian National Zoo, and the pandas are usually returned to China after a few years in the U.S.
