The Angus Thongs and Perfect Snogging actress, 28, only announced she was expecting with the Ron Weasley star, 31, back in April.
But just weeks later, Georgia has given birth to a little girl.
A short but sweet statement from the couple said: "Rupert Grint and Georgia Groome are delighted to confirm the birth of their baby girl. We would please ask that you respect their privacy at this very special time."
The pair have not yet released a picture of the little one, or shared her name.
Rupert and Georgia have been dating for nine years, first getting together back in 2011.
The couple are infamously private about their relationship - so much so, that many didn't even realise they were dating until a couple of years ago.
But Rupert hinted they would soon be starting a family back in 2018, when he discussed his desire to have children, and even pondered baby names.

"I'd like to settle down and have kids soon," he told The Guardian. "If I had a son, would I call him Ron? It's quite a good name, but probably not. And Grint's a tough name to pair a one-syllable first name with."
Rupert is best known for playing Harry's bumbling best friend in the Harry Potter franchise, first appearing on screens as a child actor in Harry Potter and the Philosopher's Stone.
He has since gone on to star in various TV shows, including Sky's Sick Note and BBC's The ABC Murders.
Meanwhile, Georgia was the lead protagonist in Angus Thongs and Perfect Snogging, crashing onto the scene in her olive costume a decade ago, and falling for Aaron Johnson's swoon-worthy character Robbie.
The pair even briefly dated in real life after the show, before she met Rupert.
Congratulations Georgia and Ron.... sorry, we mean Rupert!
