The magic between Daniel Radcliffe and Rosie Coker is gone.

The "Harry Potter" star and his long-time girlfriend have ended their relationship. Coker's father confirmed the breakup news to the U.K.'s Daily Mail, adding, "Rosie's not in this country at the moment. She's trying to move on. She won't want to talk about it."

A rep for Radcliffe tells omg!, "We don't comment on his personal life."

Radcliffe and Coker, both 23, met in 2007 on the set of "Harry Potter And The Half-Blood Prince" and started dating three years later. Radcliffe wasn't shy about his feelings for the production assistant. Earlier this year, he told Parade that he was "absolutely" in love with Coker, who lived with Radcliffe in his luxury Manhattan pad. "When Rosie's here, every day seems better," he gushed. "Ultimately, I think, it comes down to that — having somebody in your life who makes you happier than you thought you could be."

However, Radcliffe did admit that he's "not an easy person to love." He told Parade, "There are lots of times when I'm a very good boyfriend, but there are times when I'm useless. I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things. This year it's fantasy football, which means Rosie has to listen to me talking 24 hours a day about this team. 'Should I take this player out, do you think, darling?' And she listens to it, and she loves me for my oddness, my awkwardness, all of those things that I hate about myself. She finds them cute. I guess that's love."

"Keeping Up With the Kardashians" and all their business projects is becoming impossible! The older Kardashian women, Kim, Kourtney, Khloe, and even mom Kris, are constantly pitching products, from diet supplements to books to perfumes to shoes. They even have a store called Kardashian Khaos in Las Vegas — not to mention their Dash boutiques, which sell water with Kim and Co.'s faces! Now, the family's youngest entrepreneurs, 16-year-old Kendall and 15-year-old Kylie, are adding one more Kardashian family-branded item to the list: a clothing line, which is not to be confused with the clothing line that their older half-sisters already hawk for Sears and QVC.

Justin Bieber and his Adidas are about to do the illest things.

Just days after Sharon Osbourne publicly opined that Bieber's star is fading and his career will soon fizzle out, the 18-year-old has inked a lucrative deal to be the new face of Adidas.

The "Boyfriend" singer announced his latest endeavor on Tuesday morning. The two-year deal will team him up with the German sportswear company's Adidas NEO label. His official title is — get ready for this one — Global Style Icon. In addition to appearing in the company's ad campaigns, The Biebs will compile a list of his favorite Adidas products, which fans will be able to peruse and, hopefully, purchase.

For all the perks that come with being one of the starlets in the "Twilight" movie franchise, Ashley Greene admits that there are drawbacks. The 25-year-old, who's reportedly dated Joe Jonas, Kings of Leon's Jared Followill, and singer Reeve Carney, among others, says it can often make connecting with other people tricky. "I'm always here and there — everyone in my industry is — and that's why a lot of relationships are fleeting," she explains in a new interview with Marie Claire magazine. "I've gotten very good at detaching whenever I have to go away for three months, which I realize is hard on friends and kind of selfish," she says. "You go on a couple of dates, and then someone ships off to do a movie. It's not like you're going to fly out and see them, because it's not serious enough for that."

Whether they're rocking out onstage to their hit "What Makes you Beautiful," goofing off in their latest music video "Live While We're Young," or dancing "Gangnam Style," the guys of One Direction are all about having fun! The British boy banders have been known to joke around during interviews, but that wasn't this case when Harry Styles, Zayn Malik, Niall Horan, Liam Payne, and Louis Tomlinson sat down to chat with Seventeen magazine — well, for the most part. They opened up about girls, specifically a certain "X Factor" judge who's been known for her relationship with another boy band, the Jonas Brothers; the traits they've been labeled with as part of the band, such as "the bad boy"; and the one moment that two of the guys would rather forget!

Things are getting pretty edgy for a bunch of former Disney princesses. Selena Gomez and Vanessa Hudgens will soon be seen playing college girls turned bank robbers in "Spring Breakers," and Gomez recently got her second tattoo. Now, another former 'tween queen is taking on a racy new TV role.

Ashley Tisdale, best known as the musical theatre diva Sharpay in Disney's "High School Musical," has taken a completely different part on the FX biker gang drama "Sons of Anarchy." The 27-year-old actress plays Emma Jean, a high-class prostitute used by Clay (Ron Perlman) in a scheme to make his wife Gemma (Katey Sagal) jealous.

Taylor Swift really does have a problem with "Mean" people!

The 22-year-old singer has donated $10,000 and concert tickets to a bunch of kids who were the victims of a recent prank. Papa John's Pizza and Chegg, a company that offers textbooks for rent, sponsored a contest last month in which the school with the most votes on Facebook would win a live performance by Swift. Some voters from the websites 4chan and Reddit thought it would be funny if the students at the Horace Mann School for the Deaf and Hard of Hearing in Boston scored the grand prize, so they voted for the school. Then, other people heard about the mean-spirited joke and also voted for Horace Mann. After all the drama, the school was deemed ineligible in the contest, but was a big winner in the end. In addition to Swift's $10,000 gift, each student at the school will receive a ticket to her next local concert. The school also received $10,000 from each of the contest sponsors, as well as CoverGirl and American Greetings, two companies Swift works for as a spokeswoman. VH1's Save the Music foundation is also awarding the school $10,000 worth of musical instruments.

And for the record, Horace Mann's principal, Jeremiah Ford, said his students love live music. Even those who are 100 percent deaf can experience the vibration of sound, he told The Boston Globe. ""Are we the winner? Absolutely," he said.
