In his first Insta post, the 32-year-old actor revealed that he and his girlfriend, actor Georgia Groome have named their six-month-old daughter Wednesday.

Grint, who played the bumbling Ron Weasley in the fantasy film franchise based on JK Rowling's books, shared a photo of himself cradling the baby, who is dressed in a bright pink jumper.

"Hey Instagram... only 10 years late, but here I am. Grint on the Gram! Here to introduce you all to Wednesday G Grint. Stay safe, Rupert," he wrote on Tuesday alongside the picture.

His "Harry Potter" co-star Tom Felton, who played Draco Malfoy, welcomed his on-screen enemy to the social media app.
