London: 'Harry Potter' star Daniel Radcliffe is reportedly planning to tie the knot with his girlfriend Rossane Coker.

The 22-year-old actor has been dating Coker, who was the assistant producer on three 'Potter' films, for a year now.

Coker's father Malcolm has given his approval and a friend of Radcliffe said that he is considering marriage, according to reports.

"They're crazy about each other. Dan wants to marry her," said a friend.

Coker, 22, met Radcliffe while working as a production "runner" on 'Harry Potter and The Deathly Hallows Part One'.

Film chiefs worried about the schoolboy wizard's image ordered the affair to be kept under wraps until the last Potter film.

But the actor recently let it slip when he said, "I'm very much in love."
