Harry Potter star sent pyjamas

Grint, 23, said that “oriental-style” pyjamas were the most popular kind he received, but admitted that a few hand-knitted pairs also came his way, presumably in the style of his on-screen mother Molly Weasley who is known for her love of home-made fashion.

Speaking at the launch of the Warner Brothers Harry Potter studio tour at Leavesden, near Watford, Grint, who plays anti-hero Ron Weasley in all eight films, said: “I get a lot of pyjamas, it seems to be a theme, I don’t know why. A lot of oriental-style ones”.

When asked if hand-knitted pyjamas also featured the actor replied “yes”, laughing as he relaxed on the set of Gryffindor common room.

Gryffindor is one of the four Hogwarts School houses and the one of which Harry Potter and Ron Weasley are both members.

Grint’s co-star Tom Felton, who plays bully Draco Malfoy in the films, said he would like to “take credit” for Mr Grint’s appearance in the video for popstar Ed Sheeran’s Lego House single, which has been watched more than 22 million times on YouTube.
