Actor Daniel Radcliffe was spent two days in a New York City hospital last week after severe bout of food poisoning left him sick and dehydrated.

After touching down in the Big Apple to promote The Trevor Project – a suicide prevention charity for gay and transgender youth – the Harry Potter star fell ill with a stomach virus.

“He looked as white as a sheet,” said a witness. “He said he felt like he was going to die and had spent most of his time on the toilet.”

Daniel has since flown back to the UK.

Daniel says: “I grew up knowing a lot of gay men and it was never something that I even thought twice about — that some men were gay and some weren’t…I think it’s important for somebody from a big, commercial movie series like ‘Harry Potter’ and particularly because I am not gay or bisexual or transgendered. … The fact that I am straight makes not a difference, but it shows that straight people are incredibly interested and care a lot about this as well.”

Daniel’s PSA, filmed at the organization’s Wall Street headquarters on Friday, is scheduled to debut this spring.

Two young movie stars were the highest paid actors in 2009, according to Hollywood Top 40 list — featured in the March issue of Vanity Fair.

Emma Watson is only 19, but thanks to her promising acting career and lucrative modeling gigs, the college freshmen was the highest-earning actress of 2009. Emma raked in $30 million after starring in Harry Potter and the Deathly Hallows Parts I and II last year.

She was placed No. 14 on the Top 40, behind a number of film producers and directors, and fellow actresses like Cameron Diaz, Sarah Jessica Parker, and Angelina Jolie.

Emma’s Harry Potter co-star Daniel Radcliffe is even richer than she is. The spectacled star scored $41 million last year, which made him the highest-earning male actor of 2009 – beating out older actors like Tom Hanks and Ben Stiller — not bad for a 20-year-old!

How much do you think they’re paying the third Potter Kid, Rupert Grint?

Harry Potter can’t wait to become a father. Imagine that…..

Former child star Daniel Radcliffe, now 20, is anticipating having a big family.

“I’ve got kids to have yet! They’re going to keep me busy if I do – which I hope I do at some point,” Daniel told The BBC this week. “I’m not planning on it soon – but that’s one of the things I’m really looking forward to doing.”

Daniel will next be seen in Harry Potter And The Deathly Hallows, opening next year.

Daniel will play Edmund, a young vampire that captures Lisa’s heart. But Homer and Edmund’s father, Dracula, try to break up the romance, Simpsons executive producer Al Jean told Entertainment Weekly Wednesday.

“Daniel was very excited to do The Simpsons. And we kept trying to ask him for secrets from the upcoming Harry Potter movie until we realized that they were all in the books.”

Are you excited to see Daniel’s spoof?

“Daniel looked spaced out and away with the fairies. He didn’t want us to recognize him. When I said he looked like that actor in Lord of the Rings [Elijah Wood], he got a bit funny and said, ‘No, that’s not me’. He looked pretty uncomfortable. I didn’t recognize him as he looked so different to what I expected from the films. When my friend told me who he was, I was shocked.”

The actor then made a swift exit from the party after one of his photographers spotted fellow partygoers snapping cell phone photos of Daniel’s escapades.

Wadia explained: “Laura was very protective. She said Daniel had a reputation to protect and couldn’t ruin it. I presume she meant by being seen smoking. I said I didn’t know what she was talking about. But almost immediately afterwards, she and Daniel left.”

But Daniel’s rep insists he’s not smoking what the paper says he’s smoking. In a statement Friday, Daniel’s camp said: “We categorically deny the allegations regarding Daniel Radcliffe published in today’s Daily Mirror. Daniel does smoke the occasional roll-up cigarette, but he was not doing anything more than this. We are considering our position and will be taking all necessary action in relation to such allegations.”

The property, located in New York’s chic West Village, boasts five bedrooms and a 39ft long garden. The home purchase was completed last month and is the Harry Potter star’s third real estate property in the Big Apple.

Daniel — who earned a spot in the Guinness Book of World Records at the highest-grossing film star of the decade — already has a fifth-floor apartment in the trendy SoHo district and a $6 million condo that overlooks the Hudson River.

He also owns an apartment in West London.

The young stars have entered the Guinness World Records book as the highest-grossing lead actors over the past ten years after their first six Potter films earned more than $5.4 billion at the box office worldwide, according to Britain’s Daily Telegraph.

Daniel, who plays boy wizard Harry Potter, earned an average of $558 million for his work in the series. While Emma, who stars as Hermione Granger, clocked $753.7 million for her work on the big screen, which includes the animated movie The Tale of Despereaux.

The campy 20-year-old star has given the money to The Trevor Project, an support hotline for the teen members of the LGBT community.

“I am very pleased to begin my support of The Trevor Project, which saves lives every day through its critical work,” Radcliffe said in a statement.

“It’s extremely distressing to consider that in 2009 suicide is a top three killer of young people, and it’s truly devastating to learn that LGBTQ youth are up to four times more likely to attempt suicide than their heterosexual peers.”

He added, “I deeply hope my support can raise the organization’s visibility so even more despondent youth become aware of the Trevor helpline’s highly trained counselors and Trevor’s many other resources. It’s vitally important that young people understand they are not alone and, perhaps even more important, that their young lives have real value.”

He tells gay-friendly Attitude Magazine: “I just loathe homophobia. It’s just disgusting and animal and stupid and it’s just thick people who can’t get their heads around it and are just scared. I grew up around gay people entirely. I was the only child in my class who had any experience of homosexuality or anything like that.”

The Harry Potter star is reportedly dating his former Equus co-star, actress Laura O’Toole. Earlier this month, Daniel revealed that he finds it “awesome” when fans think he is gay.
