He called her a 'wonderful, wonderful girl, who's far too good for me' - but now the spell has worn off for Harry Potter actor Daniel Radcliffe and his long-time love Rosie Coker.
The star, 23 has split with Miss Coker, also 23, amid rumours that he had a fling with pretty American actress Erin Darke on the set of his new film, Kill Your Darlings.
Today, Miss Coker's father Malcolm Coker confirmed the couple had split and told MailOnline: 'Rosie's not in this country at the moment. She's trying to move on. She won't want to talk about it.'
The couple had been sharing Radcliffe's $4.3 million apartment in Manhattan
Mr Coker would not say how long ago the couple split up.
The painter and decorator from Woking, Surrey, had previously called Radcliffe a 'lovely guy' and told how happy his daughter was.
Radcliffe, who found fame aged just 11 as the schoolboy wizard, is now believed to have had had a fling with Erin Darke, an up-and-coming actress whom he met on set and wooed her with trips to London.
However, the pair are no longer thought to be together - and Miss Darke, 28, was said to be 'devastated' when the star ended the affair recently.
Radcliffe plays Beat poet Allen Ginsberg in Kill Your Darlings, set for release next year, while Miss Darke plays a character called Gwendolyn.
When contacted, Miss Darke's father Ian told MailOnline: 'I'm now allowed to comment'.
Life & Style reported last week: 'Erin thought it was a real relationship, going as far as introducing Daniel as her boyfriend.
'He’s flown her out to London and taken her on dates and spent plenty of time with her in NYC, but Daniel just up and left New York without a second thought. Erin was devastated!'
In August, Radcliffe was seen on a night out on London's King's Road with a brunette.
But the actor, who has an estimated £50 million fortune, had talked non-stop of his love for Miss Coker.
The couple met on the set of Harry Potter And The Half-Blood Prince in 2007 and speaking earlier this year, Radcliffe praised Miss Coker for helping him escape the dating game.
He revealed that marriage may be on the cards, and told Parade magazine: ‘When growing up, I thought of marriage as being very official, drawing up a contract. It seemed slightly clinical to me.
‘But then you meet somebody that you really love and you think 'actually, I wouldn’t mind standing up in front of my friends and family and telling them how much I love you and that I want to be with you forever’.’
The actor then told Heat: 'Rosie's lovely. She’s a wonderful, wonderful girl, who’s far too good for me.
'I find myself constantly going, "S**t, you don’t know what you’re in for yet'.'
Radcliffe previously dated Irish actress Laura O’Toole, his co-star in stage hit Equus.
He is currently filming his new movie, Horns, based on the best-selling novel by Joe Hill, in which he plays a young man who wakes up one morning with a hangover and a set of horns growing out of his head.
His character also has to deal with the fact that he is the prime suspect in the brutal killing of his girlfriend.
A spokewoman for Radcliffe told Mail Online: ‘We don’t comment on Dan’s personal life.’
They seemed so happy.... But this has been speculated for quite some time, so I'm not surprised at all that it's true, tbh.
