He may make the young women in the audience of his Broadway show How to Succeed in Business Without Really Trying shriek when he shakes his compact little body during his dance numbers, but there’s really only one person Daniel Radcliffe cares to succeed with: Rosanne Coker.

She’s the one the Harry Potter star described as his “girlfriend at the moment, who I am very much in love with.”

Only as late as Thursday, just as photos of her and Radcliffe strolling hand-in-hand together in New York surfaced, the young woman’s identity remained a mystery.

Not anymore.

Coker is a painter and the daughter of a decorator, reports London’s Daily Mail. Like Radcliffe, she is 22.

Other details, according to the paper:

• They met in 2007 while she was a production assistant on Harry Potter and The Half-Blood Prince.

• They’ve dated for a year, and she divides her time between her family’s $660,000 family home in Surrey, England, and Radcliffe’s luxury Manhattan pad.

• Coker’s mother Gillian, it is believed, designs birthday cards, and her dad, Malcolm, owns his own painting and decorating business. He told the Mail that he’s met and likes Radcliffe, but denied that the movie star and his daughter are engaged.
