The "Harry Potter" star, 32, joined the social media platform on Tuesday and posted an adorable photo of his 6-month-old daughter he shares with girlfriend Georgia Groome.

Grint also revealed her name: Wednesday G. Grint.

“Hey Instagram … only 10 years late, but here I am,” he captioned the selfie. “Grint on the Gram! Here to introduce you all to Wednesday G. Grint. Stay safe, Rupert.”

Groome, also an actor, is best known for her role in “Angus, Thongs and Perfect Snogging."

Recently, Grint spoke out against "Harry Potter" author J.K. Rowling's comments questioning the experiences of people in the trans community. 

"I firmly stand with the trans community and echo the sentiments expressed by many of my peers. Trans women are women. Trans men are men," Grint said in a statement obtained by Fox News in June. "We should all be entitled to live with love and without judgment."
