(CNN) If you bet on the princess, you win.

Monaco's Princess Gabriella Therese Marie was born at 5:04 p.m. (11:04 a.m. ET) Wednesday, beating her brother Jacques Honore Rainier into the waking world by two minutes, the royal family announced on Facebook

The twins are the first children born to Charlene Wittstock, the former South African Olympic swimmer who married Prince Albert II in 2011. Their birth took place at the Princess Grace Hospital Monaco, named after Albert's mother -- and late legendary Hollywood actress -- Grace Kelly.

The twins' father is the son of the late Prince Rainier III and the late Hollywood actress Grace Kelly.

"The Princess and the children are doing well," the royal family said.

Prince Albert hadn't been married before, but he did have two children born out of wedlock in 1992 and 2003.
