Fans couldn't believe it!

The pair have been in a relationship for over a decade now, but they keep it relatively private.

It is unclear when they first got together but the first rumblings that they were in a relationship was when the Evening Standard referred to Groome as Grint's "girlfriend of seven years" back in 2018.

Grint and Groome have only been seen out together a handful of times and only publicly shared the biggest milestones from their relationship — including the birth of their daughter, Wednesday in May 2020.

A representative only confirmed a month before that the pair were expecting their first child.

Following the news, one fan garnered 20,000 likes and 5,000 retweets when they announced: "I was today years old when I found out Georgia from Angus, thongs and perfect snogging has been going out with Ron Weasley since 2011????"

Groome played Georgia Nicolson from Angus, Thongs and Perfect Snogging.

Grint's claim to fame isn't only limited to his Harry Potter films. He's played a key role in Apple TV+ drama Servant for the past four seasons, and in October 2022, he appeared in Netflix's anthology horror series Guillermo del Toro's Cabinet of Curiosities.

Most recently, the actor starred in M. Night Shyamalan's latest blockbuster, Knock at the Cabin.

Meanwhile, Groome has acted in a handful of shorts, TV shows, and movies since starring in her Nickelodeon film.
